Tired

so I was just hanging out with one of my close friends (we were being super safe) and kept on asking if I was okay cause I kept on zoning out. I didnt want to ruin his mood or make the whole thing about me, so I said I was good. but when I got home I had a whole overflow of emotions because I had everything in for too long. now I really need to talk to him. but I feel like that is selfish. and I dont want to come off as annoying or needy, if he needs a break from me.
