Losing weight problems

It’s so hard. I am struggling with depression/anxiety to the point where I am in bed often. It feels dormant for me. Meaning, my depression hasn’t gone too far as to make me harm or want to harm myself or others in anyway. But it’s enough to keep me from wanting to go outside at all and barely get out of my bed. I have a 3 year old. And my husband and I spoke about another child when I was pregnant but he said in another 5 years at the time. It’s been 3 years and I haven’t lost a single pound since I had my daughter (okay I lost it and gained it right back). During my pregnancy, my weight gain caused medical issues during the last few weeks, and I wanna lose the weight so we can try again. Not only that but I want to feel comfortable again. I can’t do ANYTHING I used to. I heard how you eat can cause depression too but idk what more to do anymore. I eat because I’m depressed and I’m depressed because I eat.
