Loosing weight

I really need help loosing weight. I had my daughter almost 7 years ago. I didn’t start gaining weight til she was 4. I usually weight between 130 and 145. Now I weight 200. I don’t feel pretty or confident. I have been in between jobs the past 3 years my mom died 2 years ago from covid. I do suffer from depression and anxiety and insomnia. But I feel like my triggers causing my to be depressed is my weight. It’s hard to find clothes I feel confident in. I no longer feel pretty or beautiful. I complain all the time that I want to loose weight but I don’t know where to begin. I can admit I drink slot of soda and fast food. It’s really no excuse. I hate cooking when I’m in my depression spells. But I don’t know nothing bout working out or where to start and really can’t afford a personal trainer. I really want to loose weight and need help.
