Trauma and It is Effecting My Marriage

I was raped by 4 guys last summer. They spiked my drink and it made me numb. I was awake for the entire thing but couldn’t move. The one guy was my ex boyfriend who I loved with all my heart. My husband and me got into a fight today. For some reason I no longer saw my husband I saw my ex boyfriend Morgan. The rage inside me got to much. I screamed “if you don’t stop touching me I’m going to kill you like I should of done last summer.” I don’t know what happened or why I said that. It scared my husband and it has scared me. I’m starting to wonder if I need to be admitted into a psych hospital. I’m scared of myself and have my behavior got so out of hand. What do I do? I’m at a loss. I haven’t left the bedroom since it happened.
