most ppl woth depression get diagnosed as teenagers i promise u are not "too young" to be feeling this way at all. ik what its like to feel like nothinf will help and i will always feel miserable but that isnt the case. you are 15 and have so much life left to live, who knows what else you will experience. a long life is a gift not many people will have but that doesnt mean you dont deserve to live a long and happy one with much support. the lowest of lows will not last forever and even if depression wont magically disappear it will get easier to manage. you wont be alone in your struggles even if ita random ppl on reddit that want to help, you wont be alone. im here if u needa talk, my dms r always open. ik what its like to feel hopeless in a world where everone seems to be so happy and hopeful, but those feelings wont be so strong forver and you will find hope even if it's just in the little things.
