You know that when you drink you go 'loopy' and can not handle it, you also know that mixing medication and drink wil lresult in all sorts of problems yet you do them both anyway?
You need to spend some time on your own, sort yourself out because if you cannot look after yourself properly then I have no idea how you expect to be able to maintain a succesful relationship.
As has already been said you need to get tested for sexually transmitted infections/diseases.
And next time you feel like having a drink, just remember this and the fact that you slept with a random stranger who could have been HIV+. Scary eh?
As for your relationship, im not sure with your name whether your male or female, either way, there is nothing you can do but say your sorry and that you are stupid.
I will be getting tested, and my boyfriend. I'm male and so is he

That's punishment enough perhaps, but I don't want to lose this person.
