What should I do If I don't enjoy really my life and I feel anxious about any change in my day and I don't have any bright future or anything to do?
What should I do if I don't have anything to enjoy and I don't have a bright future to work for/ wait it?
As an extra note, I started to hate dealing with humans and I don't have any friends.
I've read through all the replys here, so I'm not gonna suggest something that's already been suggested. You've already given your opinion on therapy, and on changes/new things.
Let me start by telling you this. You say you don't have a bright future to wait for. My friend, none of us have. Your future is what you make it to be. You set your own course and build your bright future yourself, no one else is gonna do it for you. That's life, and that's what makes it beautiful.
If therapy doesn't work for you, that's fine. I personally don't believe in medication for these kinds of issues, but that's my opinion. Try meditating. Seriously, it does wonders. Start with a few minutes a day and gradually increase, doesn't have to be hard. It's gonna make you into the kind of person who takes a step back and thinks about life.
I do agree with others here that it sounds like you need to find your purpose. Purpose isn't necessarily something you actively look for, sometimes it's just something that pops into your head. For example when meditating or doing other things that don't require any active thinking.
Also, one more thing: If you don't like doing new things, try removing something. Take a digital detox, as I like to call it. I do it from time to time, and I always enjoy it and I come back with renewed energy and motivation for life. Just a few days or a week where you don't open any social media, digital entertainment (music, streaming, web surfing etc.) or anything else not strictly necessary. You're gonna be bored first, I'll tell you that. But then you're gonna find out how nice it actually is. You're gonna start craving for something to do, and if the rule of digital detox is set in your mind, you're gonna start finding new things to fill your time with. Like taking a walk or reading a book. Though it does require determination.
What I like to do when I'm in a digital detox period, is to remove entertainment focused apps from my home screen on my phone, and then put my screen in black & white (called reading mode on some phones) to make it "boring". That's definitely gonna help you.
Life is short, please make something out of it, for your own sake.
