I'm so stressed out...

I lost my baby a few months ago and was on bed rest so I gained a lot of weight. My husband hasn't had much work due to the economy and I'm having to go back to work , and honestly I'm not mentally, emotionally or even physically ready to go back but I have too. I don't know what to do. I'm so stressed out.:( I'm totally embarrassed about my weight gain also so I just feel like this is pure torture. Any advice will be aprreciated❤️
