What should i do

I recently broke up with my boyfriend of 6 years things feel really empty. We lived together and it took a lot to end things. We talk here and there about bills we have to finish paying off those moments meant a lot to me though they were short. The relationship was rough and toxic. I chose to end things and I know we can not be together but part of me feels empty. I am not going back of course but I have lost myself and idk why. My friend said I should move on I don’t know how to handle male attention all of this stuff is new to me. I have been sleeping alot I have lost joy in alot of stuff I drink alot. And I am not sure why 😭I really don’t know I try to meet new people on dating apps but I just end up ghosting them because I am not sure. I just can’t really talk to anyone I skipped Christmas and thanksgiving dinner with family instead I just stayed in my room and drank I did the same thing new years. I wish I could go back to my old self but I can not find her what should I do
