Hi and Welcome,
I also used alcohol to self-medicate anxiety and depression. I ended up being hooked very quickly.
No one but you can know if you are addicted or not. You can try giving up alcohol for a fixed period, of say a month, and see how it goes. Whether you're addicted or not, it's probably a good idea to find some healthy ways to deal with anxiety and depression. I had to get my depression treated and I've learned to deal with the anxiety for the most part.
