Depression with life and school at 15?

So I recently moved to California from mass about 2 months ago. I'm not good at making friends I'm quiet and very shy I've looked at his to make friends and tricks online but when it comes to talking to someone I freeze up. Everyday I have lunch alone. I go sit outside and eat alone then I just game on my iPhone until lunch is over. My grades are terrible because when I get home I want to be happy rather than miserable at school. I look to playing playing video games. My parents saw my grades and asked me why they are so bad. I told them my life at school and how I'm very depressed and I don't want to do homework and its hard to just do all your homework when your sad. So they took away my phone computer and I have to do all my homework and get good reports from teachers then I get it back on the weekends. But I'm still depressed everyday and I don't know what to do. I hate life at home and school. I thought about taking money and running away to San Francisco someone help thanks

Sorry to hear that you are so unhappy.
Please don't run away from home, that is a very dangerous thing to do.
Teen years are often difficult, and a lot of kids are shy, but luckily, it gets better with time.
Once you hit your 20's it'll be smooth sailing.

Look around for some people around you who seem kind and friendly, and make it a point to say Hi to them everyday.
If they're nice enough, they'll be friends with you soon.
Also, smile a lot at people, this is the best way to make friends.
Just saying "Hi, how are you?" is also an ice-breaker.

All the Best Cam!
I hope things work out for you.
