Derealization/disassociation after blacking out. What do I do?

I’m a young female and I started drinking about 2 months ago. I’m lightweight and have blacked out 3 times while drinking alcohol. Usually I throw it up and have a spotty memory but something happened on Saturday that has totally fucked me up and idk what to do. On Saturday I drank 5-6 shots of tequila and blacked out. I don’t remember a thing after drinking and my friend said I went nonverbal and was throwing up everywhere. Afterwards I felt normal until about a day later where im experienced extreme disassociation and I feel like my experiences and relationships are not real. My memory is really bad and I have a hard time remembering something unless I think very hard. I saw my boyfriend after 2 days of blacking out and felt extremely detached like every moment we spent together was months ago when it’s only been weeks. I feel like im playing myself and watching myself go through the motions outside of my body. My heart is also beating really weird and I feel slow in general, my vision is weird. There’s more detail I could go into, but I want to know if this will end and how I can stop this.
