I have been sober for similar period as you and I do understand your dilemma.
I do not fully avoid situation where there are served alcohol, that is rather difficult here as alcohol is served in many situations. I do avoid situation where I expect many to get drunk and the primary purpose is alcohol.
I is not worth risking sobriety for and if it is raising conflicting feelings you should probably be careful.
Congrats on the year, it will get easier – I am sure it will.
