Sorry to hear your sad news. I can really empathise as I went to a funeral in the first week of sobriety. What got me through was thinking about waking up tomorrow morning. Focusing on how great I'd feel waking up sober, how proud my friend would have been of me if they were still alive and here with me. It was an incredibly tough day on my emotions but I also had some great moments. I met some lovely people and had done great memories of my friend with strangers. Focus in those new liberating feelings.
Big hugs
