Trying to lose weight and conceive

Sooo my sis in law showed me a pic of myself three years ago before I had my son. I am now 61lbs heavier and am having the hardest time losing weight.

My bro in law looked at the pic and said “who was that?” ...my feelings are so hurt but it’s true. I loss my mom during my pregnancy and dealt with postpartum horribly. My son is now 1 and I’m bigger than I was when I had him. I started losing weight and found out I was pregnant this past August, had a miscarriage shortly after. It’s set my depression back big time...

Is there anything I could do to lose weight. I don’t want to quit another weight loss diet lifestyle again....

Ladies...please please please help me😩😩😩
