Pregnancy body

Just need to vent. I feel like a horrible person and my boyfriend doesn’t understand me and I feel like everyone around me is telling me I shouldn’t worry about my body because I’m creating life which I understand I really do. And I’m grateful that i can. But that doesn’t stop the thoughts in my head. Sadly the only thing I care about or focused on after I have my baby is getting my body back , I’m only 23 and took pride in the way I looked physically. But now my thighs are bigger and my boobs are a disgusting mess I can’t even look in the mirror anymore. I feel like I’m going crazy.
