I think I might be dependent on alcohol

Long story short, I lost my second baby in march this year, ever since then I drink at least a bottle of wine a night. I finish work at 5:30 and as soon as I'm done I will start drinking till the bottle is empty. I didnt think I was dependent on it until today when I finished the bottle by 8pm and still wanted more.

Please has anyone got any advice? It doesnt affect my relationship or job at the minute but I dont want to spiral until it does.

It's not as easy as stop drinking, my job is high stress, COVID-19 has stopped me doing anything social to take my mind off it etc and I didnt even know how much I was drinking till I reflected on it today.
