What's wrong with me

Every since I had my baby I have been very very self conscious about my body. Like to the point where if I see another girl that has a nice body my stomach drops thinking about how I will never look like that again. I can't even watch tv because seeing women on tv makes me want to puke. I am so jealous and envious and I hate feeling this way. I have no idea what to do but I can not feel this way anymore. I am going to ruin my relationship with my husband being so self conscious constantly. Does anyone have any advice or tips? I feel absolutely crazy
