Hi "Lost" ~ You BET you are worth it!!! God doesn't make junk, you know. So you got mixed up with the wrong person -- we've all done that at one time or another. I'm sure we've all wished we hadn't met someone or hadn't done something. I know I have some regrets. But we can't keep thinking about them -- we've got to learn from them so we don't keep repeating our mistakes.
I doubt your family thinks of you as a "burden." You are FAMILY. Family takes care of family.
And if friends didn't stick by you during a rough time you had, then I guess they weren't really "friends" afterall, were they. That's too bad. We find out who our TRUE friends really are when we're going thru a crisis.
Just take care of YOU -- once you start feeling better, the whole world will seem brighter. It CAN be a great life. God bless dearheart. Hugs, Lee
