Body changes struggle

Hi guys! So I’ve gained a couple pounds and it’s been incredibly hard on me. I am someone who prefers to be on the thin side just because it’s where my body feels best. I’m 5ft tall so any gain weight makes me feel really heavy. I am 32 now, I’ve always been pretty fit and in shape, did ballet, yoga, bjj ect. But my life is a bit different now and I don’t have the time to do these things. I’m usually between 100lbs-110lbs I’m at 120lbs and I feel horrible. I’m trying my best to be ok with this as I know bodies change and it’s really not much weight. But I am struggling with aging, the weight gain and the changes that come with it. I’m scared to enjoy food, I don’t post pictures of myself, I’m so self conscious of my husband seeing me naked. I also noticed my jawline disappearing, I got sick with covid three times and it was so severe I was in bed rest and as a result have back problems which have rounded my shoulders. My husband and I both work in the music industry so it’s hard on me to keep up with ‘beauty standards’ and being around beautiful ppl. I feel horrible and I know I shouldn’t.

I need positive advice. I need help. To some this may not seem like a big deal but to me it’s new territory. I’m really struggling with my own mind.
