How to feel better about my body? šŸ˜“

FTM and I've always had horrible self esteem issues. I had been a bit overweight before pregnancy, and now I'm gaining weight like crazy and can't try to lose weight like before. I'm on bed rest so I can't walk like I used to earlier in pregnancy. I'm 33 weeks and wanna cry when I see how much weight I'm gaining...advice? I feel bad for feeling this way and just want to feel better abler myself šŸ˜“
