Psych ward Sign up help me!!! :(?

Long story short, I'm a 16 year old teen who feels like crap 24/7 and can't sleep, hardly eats, and has common thoughts about suicide. I live just north of Philly PA and I wanted to know what it would take to get into a psych ward because I don't want to commit suicide. I love my girlfriend and don't want to leave her. (My Parents are the source of my depression so I care little for them at the moment) if you could give any information or maybe the site to sign up. Anything would help. I just don't want to feel this way anymore :'( thank you
