Want a divorce because I am depressed

At this point I am desperate for answers and what to do…I am 26F and my husband (27) have been together for almost 6 year & have 3 kids together.

I have dealt with depression for a long time, which is something that he knew before getting with me, but now I am at the point where I want to leave him because of it. I am extremely insecure now, I cry every day and I’ve been crying every day for almost 2 years, I know I’m draining him. I don’t feel like I look the same (I feel ugly as FUCK after 3 kids, even though I worked very hard to lose 50+ lbs after baby 3), I feel like he resents me but he never tells me his feelings about the relationship. Im always the one trying to figure out if he likes me or wants to be with me. I honestly feel like he’s only with me because of the children and he doesn’t want to ruin our image to others, but I am exhausted of the overthinking. I’m tired of asking him or feeling the need to ask him “where are we” because imo, a married person shouldn’t need to ask their spouse “do you love me“ and “am I good enough for you”. At this point, we’re not having sex and barely talking. We live together and he’s always home so he’s not cheating as far as I know (unless it’s in his phone and I don’t have time to look into that, for my own sanity).

Sorry if I’m all over the place or not making sense, again very desperate, and I would like advice from older married couples please 🥺 Should I just let it go?
