So question

Been feeling down recently because I’ve gained a lot of weight I’m 171 and I’m 22 years old now and I’m 5”6 I’m just so not used to being this weight usually 135 . My fiancé and I been together for 3 years now and he’s gain weight to but I don’t know if anyone else has felt this way before but I feel as though he’s not into me anymore and that he’s only with me cause he feels as though if he leaves me I will hurt myself or he’s afraid if I’m not pregnant I’ll leave him. I just been so down because of this and because of work and everything I just don’t know what to do anymore I just need someone to talk to maybe email or text idk just need someone that gets what is going on I have depression issues and there’s so much going on in my head right now I just need someone who gets me and will listen.
