Candy,
I too can relate like lots of others can. It seems that so many people are "happy" to be with you as long as the friendship is happy and good all the time. People just dont seem to want to have friendships with people who are depressed because "they are too much trouble." I have had others actually say that to me before. Remember like it was said before it is not you it is them!! If people were really good and wanted to be your friend they would stick through all the good and the bad. Not just having you around as long as you do not trouble them. That is not a real friend.
Just try to protect yourself... You are sweet and trusting and people just take advantage of that it seems.
Becareful who you really let in.

Stay strong and take care,
Jessica
