Am I under weight?

So Ive been a vegan for around a year now, and I’ve lost a lot weight. I’m 5’1 and I’ve always been a small girl but, now I feel self conscious about my weight. I don’t feel very pretty because I see so many “thick”girls. I really want to have curves but I don’t know how to get there. I wear a size zero I’m pants or a size 23. I feel like I have chicken legs and no ass lmao. I sometimes layer my tights under my pants just so they fit better, and I wear a lot of sweats and baggy stuff to hide my body. Ive even trying to eat more but my appetite is so small. I feel like I stuck in a body that’s dying. Im 97 pounds and I think I’m supposed to be like 115?. If anyone is dealing with the same problem please give advice or support.
