Work is getting hard. Things don't change

Hello, I work a job that is very "normie" oriented and mostly women besides me, and the men are mostly family men. Everyone goes home to their kids and spouse and has a life outside work. I don't have a family and my job is stressful, and my friends mostly do not live near me and I can only talk to online. I quit using drugs and now I don't have any way of coping at all. I started exercising and dieting and in some ways it makes things worse, in some ways it makes things better. I feel like I'm slowly going insane and spend every waking second glued to my phone or computer to try to distract myself from how empty and stressed I am. At work I've started doing as little as I can get away with because I just can't really cope with more than the minimum but I don't think anyone has noticed. I turn 30 in a couple months and this is not where I wanted to be, and in some ways is where I dreaded being when I was younger. I am in therapy and talking about things changes nothing, and I've taken Antidepressants for roughly half my life with no real positive changes. It hurts so much to realize that this really is all there is. I wish so much that things were different but it seems no matter how hard I try they are not going to change. Just venting
