Hello krinsi, welcome!

I don't know about it being psychosis but certainly it can affect us emotionally online just as in real life. There can be some nasty people on the internet that really don't care how it affects others because of that screen between you and other people. Yes it can feel surreal at times but being mindful of what you say and how it can really affect others is the key. PC is a good place because there are moderators that keep an eye out for the safety of the community and trolls don't last long here! Keep safe.
