I feel so sad, nothings getting better?

I'm really trying to better my life but it seems nothing is working. I am extremely lonely, extremely sad. I have joined clubs, initiated conversations with people, but nothing works. High school just sucks. I have tried ignoring the bullies but it gets on me sometimes. i am always asking for partners, trying to be positive about the whole hing but geez, kids are so rude sometimes. Plus I'm not doing too well in my physics cl and my teacher's calling home saying I should drop it. It's like damn, I'm trying, just b/c I'm not a math genius and get it so easily doesn't mean I won't. I''m worried that I won't get into any college and that I won't make it in life. I find myself more and more depressed, and I just hate going to school. I feel like nothings changed, my whole high school experience has just sucked. Plus home life isn't going to well, I don't want to get into details, but its not. I really have no one to talk to. I don't know, this was more a vent than a question....I just needed to vent.
