I dont have the motivation to lose weight anymore like I use to. Should I just give up?

Most of my family says I dont need to lose anymore weight in the past. I've gained the weight back after I lost it. I lost 13 pounds in February and I went on the scale and I put on 5 pounds back. Now I'm 239lbs. My family wins. I give up. I'll never get to 179lbs like I was in 2013. Before I was 179lbs I was 220lbs. I guess I'm meant to be big. I'm 6'1 and large framed. Some people say I dont look bad or overweight because I'm over 6ft.
Should so just give up? I move around a lot. If I lose the weight again, they will criticize me and say dont lose no more weight or I didn't think you were fat at all. Its up to you but you look better thicker. Help!
