Depressed and insecure

I honestly feel like there is something wrong with me.. I am so insecure. I had a baby 4 months ago and my body did not “SnapBack”. I feel like everything about me has changed, my hair is dry, face is breaking out and just looks different, my body doesn’t look how it used to and I’m 25 pounds heavier when I used to weigh 110. Now whenever I see extremely pretty girls when I’m with my husband I get extremely insecure and upset.. he always told me how he honestly doesn’t even look at other women and how he thinks I’m the most beautiful girl he has ever seen.. which even if it isn’t true it’s still great to hear. But I just don’t believe him anymore.. I get upset thinking he looks at other people and thinks he wishes I looked like I used to..I even get angry with him I just don’t let him know that. I don’t ever bring it up to him or let him know how I feel because I don’t want to be one of those bitchy insecure types of wives.. but I so am. I just want to believe my husband and stop feeling so down about myself.. I don’t know if I should see a psychologist or what.. I know how I’m feeling is not normal.. I just wish I could fix how messed up I am..
