You don't know how much I wish that I had been able to get some help when I was your age. The longer that you don't get help of some kind to get better, the harder it will be and the longer it will take. It is possible to find an adult who you can talk to and who will give you the acceptance and validation that you are needing, but if you had that available, I would guess that you would probably already be doing better. It might not take a lot, and there are ways to get therapy for less cost. I felt the same way that you do about school counselors (since I also went to a huge high school, and never had experiences with them that made me feel like they cared. But if you specifically go to them and tell them what you need help with, they can talk with you a few times, and might have groups available that could help you, and can also help you to find a therapist and the means to go to therapy. Why not give it a try?
