How Can I Overcome My Lonliness?

Why don't you try getting over her and find someone who isn't already taken? You are causing your self misery by focusing so much attention on a girl who already has a b/f. If there is no chance of getting together with her, you should get out and try to meet someone else to focus your interest on.

That's a hard one because everyone feels lonely at times... I'm bipolar and sometimes I can feel lonely in a room full of people so maybe someone can answer this for the both of us...

Hey,cheer up,everything happen's for a reason.Why don't you try meeting new girl's online.Go to a club and have some fun.Don not dwell on this or you will never move on.

I can only give you my perspective, from a place where I have been alone also.  Sometimes it's only in looking back that we can see that the alone times are exactly right to do other things -- to make ourselves ready for what we don't know is coming.  I think it's human nature to want it NOW-- to feel we are SO ready for that person.  Meanwhile, if you can just trust that where you are is EXACTLY where you need to be--that there are  things to be attended to in yourself while you wait-- gosh I know it seems impossible and senseless while you're in that place-- but really, you will find there is a good purpose and much to do in the quiet times before--and if you can make use of this time, it really will be seen as a blessing when and if you connect with just the right person.  

This is maybe the best time to make plans and take inventory of what you need--really what you need, and what you really want to DO with your life and to be.  I know it can ring hollow to say this in a time when you are feeling lonely, but truly, if you've got this part down--what you are, what you need, what you want to be and do, it leads you to EXACTLY the right person.  I promise.

For whatever it's worth, I find it's rare that we can appreciate the time alone--maybe it's human nature to long after what we desire and expect.....Have found most of us who have been alone for whatever reason (never met the person, lost the person, etc) only find the value in our time alone AFTER it's over.  So I can relate--but if you can, I hope you will trust there is value in this time alone.  She's on her way to you--and You can be on the way to you also...  Keep the faith.
