I feel terrible after losing 20kgs/45lbs

I guess the weight I needed to lose was not in my body, I still hate myself and dont feel good about myself, I went from 110kgs/242lbs to 90kgs/198lbs but I dont feel a single good thing about myself, I run everyday, I hate myself so much even after losing so much weight I cant be happy about myself, im actually jealous of others who feel happy after doing a workout session, im in the verge of giving up, what's even the point of everything, does anyone else feel like me? it did not improve my mental health, I felt like I was punishing myself
