I must be over emotional...

Well the kids are napping, and I went in to just peek at them, and I wanted to cuddle up to them and hold them without letting go. My days are going well, it's just the not sleeping and crying at night that is getting me down. I must be depressed because the 28 pounds that I lost, I gained it all back, and I feel like all I want to do is eat junk, and it makes me feel better for the time being. I don't want my kids to leave, and I just don't know what to do, or how to act, or what to think, and I keep this all buried inside. I feel that I have no one to turn to about it because I don't want to seem weak, or complain too much, but I need someone to talk to about this without feeling judged. I'm scared I may break, and then it will truly be over for me, and any chance of a life I have with my kids.Is there anyone who can give me some advise,or anything. I'll try, but I feel my faith slipping, and I need support. I feel I've drained everyone I know, and I just want to make it all go away. What a life I really have been a screw up, and messed up things for alot of people. I don't know why I even have my sister by my side still. I feel that I'm a helpless cause, whatever I guess...
