Help , advice on marriage


I’m lost , I don’t know if I should fight to keep my marriage together or let go . It’s been a year , we got married after only a year and for some time now I’m just not happy . Im scared to let go cause i don’t want to hurt him but I’m not even affectionate towards him , we barely have a sex life anymore but then again we never really did . Idk if i just married him because i thought it would help me but it seems like I’ve gotten worse (mental health issues)

I don’t know what to do . I’m 21 years old and I can’t go to my family because they all love him . He isn’t a bad guy , but for some reason I’ve just been so unhappy .
