Hi Adam,
I am so sorry that you are feeling so isolated.
Congrats on your sober time ! Well done !
I , too, have just started holidays, and I am a bit like you , if I allow myself to isolate. I make plans, then cancel them. For me, it is "old behaviour", so I need to be on my guard. If I let it go on too long, it gets SO hard to make the effort to change it .
My solution is to ring AA friends, and SHARE how I am feeling,lunch with my Sponser , and I always "up" my meetings during my holidays too, cos I used to dread them when drinking.
I make plans with AA friends to have coffee, see a movie, or take the dog for a walk ! LOL
It does take a huge effort, but I know that it is what I should be doing, and that I will feel better for it .
Hope some of these ideas help. once you take the first step, it wont be so hard
HUGX
