It's pretty normal to dislike all of your neighbors, not ideal - but normal. To me it sounds like you may just be ultra sensitive to the energies of other people, which I can relate to. We often think it's normal to have to live under "one roof" with lots and lots of people, but that isn't inherently true for a lot of sensitive folks. Energy exchanges happen, and they can majorly affect people until they learn to manage what it is that bothers them. Some people are way too affected living with/around other people, and that's okay.

Knowing what your triggers are, and finding a way to understand them or avoid them has been key for me and my current disdain for 2 of my neighbors.

Also, taking supplements for anxiety has helped tremendously. Such as: Shoden Ashwagandha, and L-theanine. r/nootropicsdepot was a huge resource for me in finding help with these supplements.
