Roughly where are you? My family member (FM) was drinking the same amount as you but was physically dependent. She was referred to the local addiction clinic via the GP but we found out later you can self-refer and they’ll do phone appointments/video calls if that’s easier for you.
FM started like you, literally going from home to work and back, too anxious to even visit family and avoided medical professionals completely. She used the referral to the addiction clinic as a (very slow) gateway to help from GP, MH services and a counsellor.
If you have this service near you, I would definitely advise you to access it.
If not, would you consider counselling? Lots of people offer online video calls etc so you wouldn’t need to go out.
On a practical level, can you limit the amount of alcohol you have access to? Initially FM was advised to open a bottle of wine and pour away 1 glass then drink her usual 2-3 bottles, then increase the amount she threw every 2 weeks. She needed help initially but it gave the clarity needed for everything else.
Do you have any old hobbies you could pick back up? Drawing, sewing, knitting, walking, puzzles, gaming, yoga, anything you can do to keep busy in an evening?
Friends you can lean on who will come over/you can visit/meet for a coffee?
Is your partner aware of your drinking and that you’d like to cut down/stop? Does he drink with you?
Essentially in my (very limited) experience, it’s very hard to stop alone so if you have support, you should use it.
And your struggle to simply be at home, relaxed without drinking indicates the drink is being used to ‘help’ in some way and if you’re not sure how, it may be that you need a counsellor to help you (my FM was drinking away absolute rage and frustration with her life but didn’t really realise this until the drinking had stopped).
If you’re not ready for all that, keep reading the quit-lit. Look for podcasts about getting sober. Use the threads on here, they’re very supportive.
Good luck OP 💐
