I have chronic depression, anxiety, complex PTSD, OCD and Borderline Personality Disorder. I got drunk last night at home with my partner. I don’t normally drink because it does mess with my mental health a bit but I felt safe and comfortable being at home. My partner went to sleep and I went out for a smoke. Next thing I remember is I was punching the outside wall of the house and laughing. Then I went Inside and got a knife and cut up my legs and arms and was still laughing and grinning. I had split but it was scarier than normal because the person who was in control was scary and so unstable and destructive. I don’t remember much time there but my partner said I was in the bedroom screaming really loudly and woke him up. Then I ran around the house saying the demons got into the house and they were after me. He got me to calm down and get into bed and he said I was asleep pretty quick. My head has been messy today and I’m just worried about what happened. I’ve never had an episode like that before. Is this normal or is something seriously wrong with me??
