That really sucks to hear man.
There is a lot of sound advice that will be wasted on you right now. Time heals all wounds, though you usually don't want to hear that during the time.
You've hit a rough spot and your in a different environment and state of mind to the self you've always known, but what really matters is what you do.
Changes oft come at the lowest points in our lives, and when you're down on your luck with little to loose why not try make changes?
The thing I wish you would think on is that school, hobbies, social circles and relationships aren't actually always a big deal. If you can shift your focus from a longing to have the same mundane existence as the people around you, who think they have it right, you can really make a difference in your life. Find what's important to you, maybe meditate for a while and think about life, existence and the nature of our reality. Find what you care for and embrace it. School doesn't matter for stuff when you leave, you won't see 95% of your schoolmates after you graduate, relationships are feeble and you're still at the starting line of life.
When people are able to shed their unnecessary, socially influenced and completely ridiculous worries and strive for themselves and what they care about, they exude a magnetism that attracts not only people, but happiness.
There are a lot of different people in the world, and not all can see things the same way, but I hope you can see things through a clear lens and shed your strife.
I was excited to see you posting here again, I feel like I haven't seen you here for a long time.
I hope the best for you Skate.
