ok. So, I'm also depressed. No joke. Please don't kill youself. It is something you will really regret. Your boyfriend is probably hurt because you told him you feel alone, but I'm sure he really cares about you. Please try to talk to him again, saying what you said here. Also, talk to your family. I know that at times they can be so annoying but they care about you. If you don't feel like they do, you need to call your friends. At this time it's important to talk to someone that knows you, so they can remind you of your goals and plans, things to stay alive for. I don't think that ending up in the hospital would be good, although then people would certainly understand what you are going through and you will find out who your true friends are. With all that medication though, you will kill yourself. So please don't do anything like that. Call your friends, family and boyfriend. Live for tomorrow. Something great will happen, I know it because that's how life works.
I know how you feel, I hate everything, I hate school, my friends and myself. I don't even have a boyfriend but I really, really wish I did. I have one friend that I love and trust and once this is all over, I know I can rely on her but if it wasn't for her I'm sure I would already be gone. Think about this person in your life, if you don't have anyone like this, reach out and you will find them. Then, talk to them. Listen to My Chemical Romance, they helped save my life with what they have to say.
Good luck and PLEASE DON'T KILL YOURSELF.
I would be really, really sad and I don't even know you in real life, imagine how depressed everyone who really knows you would become.
I love you.
