Extra skin

I lost 80 lbs a few years ago and put back about half of that weight. I decided this year to take my health back and joined this program. I have been doing no flour no sugar and am seeing great results with my wight loss so far. Today i looked at myself in the mirror and hated all the extra skin I have in my belly. I think this was one of the reasons I wanted to put some of the weight back on. The thought is “why bother if your stomach is going to look sooo much worse anyways”. I am not aure where to go with this thought to a better place. I have tried “its still worth it”, “i love my body” but I just cant shake this desire to go into apathy and quit since I have so much excess skin. Any tips/feedback about how to deal with excess skin and also keep going would be appreciated. Thanks in advance.
