Looking for advice. What’s going on with me?

This is very vulnerable for me to post, so please be kind. I’m a 28 yr old female. I’m struggled all my life with executive function. I was finally diagnosed with ADHD Inattentive Type around two years ago. I’ve always shown symptoms, but I’ve masked them from my friends and family. I also was diagnosed with depression around seven years ago. I’m struggling right now and I don’t know if it’s because of my depression or my adhd or if I have something else. Basically, I got fired from my job a year and a half ago. I was unemployed for six months and could have found a job way earlier but I just stopped looking at one point and gave up. Eventually I got back to it and found a hybrid job. Since this job I’ve gained 20 pounds. I don’t go to the gym because I can’t force my body to go even though I know I need to. I also just sit at home and do nothing because my body can’t make me do anything unless I’m hanging with friends. When I’m not with my friends, I am instantly bored but will not do anything about it except play on my phone. I barely ever cook because I get “bored” to cook actual meals. I just eat granola bars and quesadillas and yogurt and basic things or I go out to eat where I eat actual healthy food. I also don’t shower regularly and don’t brush my teeth regularly (this has been like this since a kid and I believe it’s from my adhd). I haven’t been to a dentist or doctor in three years. I have a stack of mail that I haven’t opened in almost a year. I have bills I haven’t paid. I don’t preform my best at work. I am off of my antidepressants that I used to take but I still had these symptoms when I was on the meds. I do take my adhd meds but only when I feel like taking them. I do not see a change when taking my meds even tho I’m on a high dose. How to a fix these issues about myself? My friends do not know this about me. My parents do not know either.
