How Do I?

How do you stand back up on your own two feet?

You've lived all your life being rejected, you don't know why. You feel unliked, unwelcome, unloved.

You don't know what is up with you, what did you do wrong? What else can you do to "change"?

No one is saying anything, it seems fine but then... Its still the same, or even worse than before.

So, how? How do you move on and learn when you don't know what there is to learn, or how.
