I have recently realized doing favors is something I really hate, when it's the same person that keeps asking for favors. The thing is, I'm not sure if it's some overthinking bullshit(struggling a lot with overthinking) so when someone asks for a favor after like 3-4 times I start reacting and say "do it yourself", but I usually get an angry reaction. I get it that doing a favor every now and then is alright and I have no problem with it, but some stuff like "can you put my phone on charge?" or "can you do this and this"(it's some simple thing they can do on their own).
