I almost blacked out last wednesday, got really drunk but not black out last Friday, and got drunk last saturday and now have some questions

Ok so I almost blacked out last wednesday, got really drunk but not black out last Friday, and got drunk last saturday. Then half way through sunday I started having trouble focusing and remembering and my brain felt foggy, I also realized when I pinched myself i could feel it but it didn’t hurt as bad. Now it’s this wednesday and I still have these symptoms and am wondering did i damage a nerve and will Inhave these symptoms for ever?
