Sorry to hear she passed, stay off the drink I know it feel it helps at the time but it only delays the time it takes to learn to deal with it and get on with life.
Won’t lie it never ever truly gets better you just learn to deal with it, probably will always be a hole in your life and will change you but you can be happy again just things are just never the same as a few on this board have mentioned over the years (kwon, army ect), not saying this to be cunt just to give a realistic expectation of how things will be, it’s over 5 years since my dad died and I still miss him and think of him multiple times every day and could easily cry at his memories if I let myself
Take care
