These are natural and normal feelings of grief that are resurfacing because you never dealt with them previously, you suppressed them with alcohol. I am so sorry for the loss of your daughter and the terrible sadness you must be experiencing.
What's weird is that after I quit using, I found that not using was not the hard part for me. Dealing with all of the backlogged emotions and feelings that using covered up is INCREDIBLY difficult. Yesterday I cried almost all day. But I FEEL better and know that I just need to work through these things, as overwhelming as they may seem.
