depression has taken over me

I've been going through depression since the past 6 years. nothing feels normal anymore. I've lost my spark, friends, the loml, my family & myself. at this point, its hard for me to let a cry out I've been overdosing on my psychiatric pills but nothing helps. I've a fuck ton of exams coming up but I've been bed rotting from an entire month, its like i have no motivation left :( i wonder if life will ever get better. tbh i dont even remember the last time i was truly happy and enjoyed life.
