I Have Been Feeling Very Said And Angry Lately. I Always Wanna Cry But I Dont Know Why. I Get Mad Over Anything. I Used To Be So Happy, Im Always Lashing Out At My Mom And Everyone. People Have Noticed A Big Change In Me. I Dont Really Know Why?

I suspect your problem is what we older people call an age issue.  When you are a teen and most especially if you are a girl, hormones come into play.  They rage and cause all sorts of emotional issues.  You can go one minute from being a happy, carefree young lady to a screaming shrew.  My daughter and granddaughter would cry if you looked at them wrong.  What you are experiencing is part of growing up, unfortunately.  These raging emotions will pass in time.  Until then,  about the only thing you can do is realize that you have a problem and try to deal with the problem.  When you feel yourself getting out of control, tell yourself, "I have the ability to control this."  You can control yourself if you are aware of the problem and want to take control.  Right now, you apparently don't like what is happening in your life with your family and friends.  Only you can do what must be done to stop these outbursts...be aware of your emotions & control them.  Do not let them control you.  You can do this.  Women all over the world have dealt with this very problem for generations.  If they can manage to rein in their out of control emotions, you can also.  I believe you are capable of making it work.  You seem to be a very stable,  aware person.  Make it work for you...you can!

Ok but im not a teenager, im in my late 20's, it happens to me quite often, not sure

Simple. Its mood swings, they change you completely. But you will soon learn to control it. Well you'll get the hang of it.

I act like that all the time maybe someone you love is gone. R u stressed out? Just don't think about suicide your Mom must really love you? Do something nice for her and just remember you can tell her what ever it is . I feel like I hate my mom but deep down I love her. Just don't get mad at her all the time

It is just growing up ... Becoming a teenager...its up to you if you want to calm down...maybe you should start reading? Are you tired?....try catching up on sleep.... Is something up at school??? I dont know but you do....maybe you should think about that
