There are some practical steps you can take to help you begin to realize your worth once again and regain a more positive outlook on yourself.  The trick is to make and see even very small successes and first make friends with yourself.  You can begin by 1) consider one area in your life where you have excelled or added to someone else's happiness.  Dwell on this thing.  2) Choose the quality you have that brings you the most pleasure.  It brings you pleasure because you are good at this thing.  Consider how valuable this can be to yourself and to others.  3)  Practice using this quality or talent as much as possible.  Because you enjoy it and you do this thing well, you will easily see the repeated successes you have with it.   Consciously notice this positive quality in yourself.   4)  Make it a goal to do something every day that will make another person's life a little better.    These might be things you say or things you do.  They may be very small things.  The size of these things as they appear to you does not matter.  To the  other person, these things were very big.  Always take a moment each morning and every evening to remember five things you said or did.  Congratulate yourself on doing these things.  5) Be realistic that all have characteristics that can be positive or negative.   Treat yourself kindly and forgive yourself for being human.  If you make mistake, you can see this as the chance to learn and do differently next time, knowing all humans make many mistakes.  It is only a mistake.  You can apologize and move on.  Making mistakes is not the definition of you, my friend.  6)Surround yourself only with people who uplift you whenever possible.  There is no place in your life for people who are set to bring you down.  7)  Again, be kind to yourself.  Think of yourself as a friend.  If you had a friend who was feeling down, what would you say to them to encourage them?  What would you do for them?  Then do these things for yourself, for you are the best friend you will ever have.  8)  Choose one small area you would like to improve upon.  Identify small steps you can take everyday to change this thing.  Make a plan of these small steps.  Maybe for example you aren't as honest as you would like to be in all situations.  Make your vow to keep your integrity, starting now.  Make a promise to yourself that the next time you are tempted to stretch the truth that you will be strong and resist it, because you value yourself and your integrity.  If you have a trusted friend who can help you with your small steps, let them know what you are working on, for they can ask you along the way how you are doing and if you are struggling, and may be they can also help you think of how well you are progressing and even new ideas.  9)  Celebrate your life and do something everyday just because you enjoy it. All day everyday we are doing things for other people.  You must take time to love yourself, because you would want this for anyone you love.

 First and foremost you have to accept your positive and negative characteristics. You have to accept yourself as what you are and start loving yourself. You will soon discover the change. You have to find some excitement to change your thinking. Pick up your old forgotten hobby or travel to some new place. Meeting some one you like and making new friends can bring some relief.

 PB...  The point of living is giving.  The more you give to others the better you will feel about yourself.  Start small.  But give to just one person without the expectation of receiving back.  Karma will find you eventually.  Just keep giving to help others.  The joy you feel in making a difference in another person's life will envelop you, maybe not right away.  Sometimes it takes a little a while - but keep helping others.

 Sounds like you may be depressed. Have you seen a counselor yet? Some of the things I do to help me raise my self esteem is to look at the things that I'm thankful for in my life. I've raised three great kids. Now you think of something you've done. Have you done any community service to help others? You should be proud of yourself. Peace

 Ok - here's my advice - stop thinking about yourself and how much you hate yourself. Think about what you could do for someone else to improve their life. Then go and do it. Anything at all. Keep building on that, and then you will find that you have plenty of things to like about yourself. Try doing a small thing to start with, like sharing. Next time you buy a bag of chips, share it with everyone in your office or wherever you spend your time. Next time you make a cup of tea or coffee, ask around who else wants one. Don't go crazy buying stuff, that just reeks of desperation and people will think you are trying to buy friendship. Just be gentle about it - share what you have with those around you. Make a special effort to do it all week. See how much better you feel after a week. Then next week, do something else, like offering to help do something for someone. The more you writhe around in self-recrimination, the more you will find things to hate about yourself and it will just get worse. You need to forget about the past - start afresh RIGHT NOW. Go and make a drink, and offer to make one for someone else, OR phone one of your friends or relatives you haven't spoken to for a while, just for a chat to see how they are. And don't spend the whole conversation moaning about yourself - try to forget that and concentrate on going outside of yourself and your negative feelings. Concentrate on them and how they feel.
