My life sucks

All I do is go to school where I have no freinds then come home to watch shit like youtube and reddit which I get bored of and play the same stupid online games which also get boring and then I go to bed to repeat the same process over again. I feel like I'm one of the few people in the world who lives like this every kid in my school has freinds even the unpopular ones have a few but I have none. I used to have freinds but I stopped hanging out with them so they stopped bothering to talk to me is it my fault? I never go outside but I guess that's my fault but the problem is I don't want to. If I'm this miserable as a teenager my future life as an adult will totally be shit. I get shit grades in school as well so I Have nothing to look forward too.
