I have never had a drinking problem until now .

I don't drink often usually socially every couple of my months or a random spontaneous night of wine at home but recently I had to end s relationship with my love in boyfriend who I love more than I can even express and I'm not drinking all the time but in the past month since we broke up I have tried to be more social do more things with friends and have nights in where I have wine and Netflix and dinner but the past few times I've drank I have s mental breakdown every single time and completely come unglued . I cry for hours and hours and I can't eat I don't sleep I guess being emotional and mixing alcohol just brings everything to the surface I just truly don't know how to get past how devastated I am . What can can I do ?
