I don't hate everybody but I hate everybody. I just have no feelings anymore and am bored all the time. What should I do?

Hmm, (to me) this seems to be a feeling of apathy more than hatred. I think hate may be the wrong word. If you've been feeling this for quite a while, maybe try talking to a mental health practitioner/professional. Sometimes these things can be more serious than you think, and there's no harm in going for a checkup. But apart from that I would recommend trying a new hobby or sport. Going outside for some fresh air/change of scenery may help. Sometimes having too much time to yourself can result in a lot of overthinking/lulls in energy. If you feel you don't have any interests/hobbies that inspire you or give you enough energy to actually do them, then maybe give a new activity a try. Trying something you've never done before can result in a lot of new experiences, and maybe pique your interest and get you mentally moving again. Hope this helped :)
