Hi there and welcome! I know just how you feel. Boredom can be a more powerful force than anyone can imagine for an alcoholic. Surely have been there many, many times myself.
In addition to all the other fantastic voices of reason re: make plans, find the key to not having the first drink (my kryptonite), reach out to your local AA. Having people around who understand is absolutely essential for me. Isolation = drunk = eventual death for me, so even if I don’t feel like it, I ask for someone to help even if it’s just an afternoon coffee or tea. You’ll feel productive doing something positive for you sobriety. It gets easier each time!!!!
And again, kudos for your honesty here :-) lots of support and understanding on this fantastic site
