I shot an airsoft gun

GUYS HELP!!! I was playing with an airsoft gun, and thought it was empty, so I put the gun right toward my dick hole and I pulled the trigger so I can get some air. But what I didn't know guys, was that it was loaded and shot a pellet up my urethra and into my left testicle. My left testicle is twice as big as my right and is quite painful. I need a home fix so I don't tell my parents about this. PLEASE HELP ME!!! PRAY TO LOGAN PAUL, KSI, AND MR. BEAST FOR ME!!!!
