Insecure in the bedroom... HELP!

So.. I guess I am just looking for a little bit of positive advice here. Im a bigger woman (25yr old) and have been since just after high school. I started putting on more weight uncontrollably just after I got married in 2011. My husband is on the much skinnier side than me and it makes me feel unsecure. I absolutely hate how I look and feel about myself.

Anyway, I delivered my daughter 5 weeks ago but before I got pregnant with her I still had baby belly from my first daughter. So now.... after 2 kids I can't even look at myself naked and don't expect my husband to.... but I'm horny all the time. And I'm sure my poor husband is dying. There are days where I try to dress cute, do my hair and make up and try to boost my confidence. Now I'm ready to make love but Everytime we try I get depressed and can't seem to get in the mood which makes him go soft.

I don't blame him. What man wants to sleep with a cry baby?! This sucks because my husband is absolute fantastic in bed!! Damn!

I guess my question is- has anyone else been in the same boat and what did you do to boost confidence so you could have sex/make love with your partner and enjoy it and yourself? Just looking for some positive ideas/suggestions. I'm already a mess from these post baby emotions and previous self hate. Be gentle. Thanks ladies.
