Whats the most painless way to die.?

sup. my life is going really bad right now. my ex-girlfriend played me. i dont go to school. im basically a failure all around. im gonna end it soon. im too scared to go through pain so i dont wanna feel anything. i know gunshots to the head work but i dont really have a gun with me. and i know about the potium cyanide thing but i dont have that either. all im really available to is my prescription prozac. and my moms pills. should i just take like a whole lot of it at once and hope for the best? help me out
