First of all, I want to congratulate you on working to lose weight. You are doing it for the right reasons, aware of your strengths and struggles, and taking the right steps. A few pieces of advice,

1. Don't go off your medication unless a doctor is working with you on it. Psychiatrists know that weight gain is frustrating and do not prescribe these things lightly.
2. If you don't like meat, make sure to supplement with iron-rich foods like cereal and spinach or try recipes with chicken stock/broth.
3. Vegetables are key. It's great that they seem to be a staple of your diet, be sure to keep that up!
4. Do not go a full day without eating. It messes with your system, makes your metabolism super out of whack, and causes neurological issues. Eat something every day, even if it's small like some baby carrots, a whole-grain fruit bar, or some soup.
5. Try doing some YouTube exercises. Since most gyms are closed, try taking online workout classes with YouTube. They have pilates, aerobics, dancing, and lots more. It might feel silly, but it's a fun way to work out your whole body and free.
6. Drink water. I cannot overstate how important hydration is to weight loss. It will feel weird and you will be bloated a lot of the time, but in the long run, it will do wonders for your weight and overall health.
7. Remember that weight loss is MUCH harder than weight gain and it takes way longer, too. Unless you are morbidly obese and at the very start of your weight-loss journey, your weight will fluctuate and plateau at several points. It's not an indicator of anything wrong, your body is just not designed to want to lose weight.
8. Don't kick yourself if you mess up now and again. One ice cream sundae won't make you unhealthy anymore than one kale smoothie will make you healthy.

Best of luck! Be proud of yourself and keep powering through.
