How am I supposed to deal with depression without the money for therapy?

I have been depressed for a couple of years now, but now I am at a ultimate low in my life. I used to have very depressive episodes, but I also had slightly less depressed episodes in between. But now, for almost a year now, its just not getting better, like it used to. I dont enjoy anything, and Im not even talking about my hobbies anymore, watching youtube videos or scrolling feels like a chore to me. I cant study at all, it has always been a challange for me because of my ADHD, but now its literally impossible for me. My brain just refuses to soak up the information. My suicidal ideation is present in almost every minute of my day. I have school and afterschool activities, but I dont really enjoy them anymore, and I used to love them. I dont laugh at comedies that used to be funny to me, I havent felt interest in any kind of romantic relationship for moths, and I feel numb all the time. Even though eating feels like a chore, I still overeat. Im just a teenager, and my parents dont have the money to send me to an expecive therapy, and they dont like the idea of me getting on antidepressants, so I dont know what to do, really. I searched online and it said to eat unprocessed, sleep well and excercise, yet dont withdraw socially, but I am pretty active (dance and gymnastics), I am not in charge of the food in house, I sleep more then I should, and I find it incredibly hard to connect with people normally, because people usually find my personality strange, I guess. I just dont know what to do. I dont want to live in a life that doesnt get better, when I just dont feel or do anything the entire time.
