I feel fat. Need advice šŸ˜”

Hello everyone. I'm not feeling good today. Maybe it is stupid but I feel fat. I used to exercise a lot, going to the gym and eating healthy and I was able to drop almost 20 pounds. I haven't been able to go to the gym, I feel without energy and I gain 10 pounds back. Could you please ladies give me some advice on how to motivate in exercising again? Also, could you give me some tips? My mother in law (who always criticize everything I do says "you are gaining weight) i wouldn't pay attention to that but a few years ago I weighed 175 pound then I was able to drop 45 pounds and when someone tells me something about my weight I feel like crap. I need some motivations. Thank you some much!Ā
