I Am Sick of Feeling Depressed

After having my 1st and probably worst depression experience I've been having the feeling again. The other day several friends and I hung out and since I sucked at every sport we have played, I started to feel useless. No one wanted to play soccer and my Asian friend said "no one likes soccer your beaner". I've been eating alot but in a non healthy way and my school grades have been affected. I've socialized less with my friends and I still talk normally to my parents but been in bad mood lately.
