Hey depress, I think this is the hardest thing many of us have been through.
The fact that he is spending more time at your house is a positive. I know how hard it is. Keep following Sandi's rules it does get easier. Make sure you look and smell good and don't mope around or let him see you angry or upset. Also, if you can, don't avoid him, do what you do...cook dinner, play with S2, bake cookies....whatever, maybe something different. OR if he's there ask him if he minds watching the kids for a bit while you "run an errand"....I'm not very good at the 180's but this is good time for you to try some of your own!
Fogg is right tho, this has to be about you! What are you doing for you?
As far as the depression and anxiety the best advice I can give you is go to your Dr. I know for me I really struggled with having to take meds but I'm glad I did. I also was having really bad anxiety attacks, sometimes the breathing just wouldn't work so i got some anti-anxiety medication as well as anti-depressants. I only took the anti-anxiety 3-4 times but it was a big help. Still on the anti-depressants for now. You have to do what you need to do to take care of yourself and your kiddos!
Hang in there!
