bullying / weight loss

I'm new to this sharing , so I figured I should probably start online before in person .. I'm 18 years old & weigh 140 & im 4'11 and I've been trying to lose weight for a couple of months I just keep giving up .. & it's so hard Bc my own family makes fun of me Bc I am trying and they just make it so much harder ..& to top off all my depression when I was younger a lot of teens always asked me if I was a guy / girl ? Or that I looked like a she-man . & 4 years later (today) someone very close to me I had a she-manly face and it just bought so many memories and I just don't know what to do everything I do goes downhill
