Is anyone else like this or am I just being mean?

I speak a lot to people online (I'm much more comfortable with this than in person) but sometimes on random days i will just get so internally angry while they are speaking, usually it's while I'm doing something like just recently playing a game while chatting with a friend. I was fine while we were playing together but when we started playing separate games and he kept talking I just wanted to tell him to be quiet and in the back of my head I feel bad because I care about our conversations but sometimes I just need silence. I feel like i get annoyed too easily but this has happened with two of my friends now and I dont know if it's just me, if I'm just a bad person.

Recently I've also been on some new medication and one of its side effects is that it makes me super tired, I dont know if that contributes to it any but it has been worse since I've been on this medication. I just dont want to change how I've been doing stuff because I've been so tired, I literally slept the whole of yesterday away because of it and I hate it.
