(seriouse) What advice/words would you like to share with a highschooler?

I have depression and im trying to work thru it but its annoying at times, also somtimes i get depressed an horny and that is just so worse, hormones are dumb. i do online school and im currently failing becasue i feel unmotivated to do work and i feel like nobody understand me, i feel like a nobody and i want to do so much but its hard to even start becasue i tend to dream big or complain online alot but im trying to improve slowly.

so what advice that youve gotten over the years would you like to share with a highschooler who is limited and stinks at most things.

i could add more but i dont want this post to go on forever.
