quick vent lol

I'm really jittery today and I have been for a while and I've just been having this overwhelmed feeling hanging over me for like three days in a row. I'm not really sure what the issue is but its really getting to me. I've been more anxious and less talkative lately. one of my friends has mentioned that and seems kind of irritated by it. I told my partner I would vent to him but I'm not even sure what to tell him. he's expecting me to tell him that something happened, not that I just "have a bad feeling" for no reason.
