Need Guidance

Hello everyone. Id like some insight into what others thinks. So growing up i had severe anxiety, and OCD as well as some pretty bad depression at times that i never truly took care of. In late may i had a severe anxiety attack that made me just feel strange ever since. My OCD my whole life has been about self harm and hurting things but ive never planned to do it or wanted too its sorta just always been the thought that its actually possible. Since that attack in May things have gotten progressively so much worse. In July i started to feel better, was going out and doing things and having fun and then had accident where i injured my spleen and went to the hospital for a few days. During this time in the hospital i was so stressed, wondering if i was dying and just constant terrible stress. Since i got out everything has been terrible and this past week especially has been so bad. Last Wednesday i began to existential think about crazy stuff. Stuff like what are humans, why are we here, is this all real or just an image, who am i, why am i me, what is reality and what is existence? All these questions and since then ive felt completely gone. My world just feels so weird. Nothing at all feels real, nothing. This has heightened my OCD so much because of all the thoughts ive always had about hurting myself now you bring it the factor that since it feels so fake what would it even matter if i did. I feel like im losing touch with reality and losing my sense of self completely and im really scared. Is this all normal? I feel as if im losing my mind and slowly drifting away.
