Do I have a problem?

I (30F) have been reflecting on my relationship with alcohol and it's made me wonder if I might have a problem. I've always struggled with sadness and loneliness, and in my 20s I turned to drinking as a way to escape those feelings. Unfortunately, it often led to me blacking out and having sex without any memory of it. I developed intense hangovers and vomiting became a regular occurrence.

During a particularly difficult relationship, I became severely depressed and stopped taking care of myself. When I did go out, I would drink heavily to feel happy again. It was hard to control myself and I often woke up not knowing how I got where I was. Eventually, I found a job with a great boss and started feeling better. I began hooking up with guys who treated me well, but I still drank a lot and did things I'm not proud of. Now, I have a boyfriend who helped me realize that my drinking was becoming a problem. But I still drink. How can I overcome this?
