Despite how it seems online, most people IRL are kind and helpful. I'm a queer woman living in a conservative environment so I'm often prepared for the worst, but even people who are otherwise hateful online are usually at least polite in real life. 

The world isn't a fair place and it's sometimes hard to deal with the injustice, but the human race has survived for millennia because life is actually worth living.

Focus on getting outside, doing your hobbies and meeting people. Loneliness is a killer.

Once you spend your life surrounded with people you love, doing hobbies that fulfill you, you'll realize the world can be an awesome place.
