A clear head forms the best conclusions. If your mind is kind of messed up, just be careful about forming conclusions based on a temporary emotion. You reinforce this kind of emotional input through joining things like echo chambers. The reason that people break up with you has nothing to do with you and has everything to do with them. They'll even say, it's not you, it's me, that's the self aware person who actually it is you. And it's not them.
