You’re already doing better than a whole lot of people if you’re getting invited to parties. Of the people I was at school, university, or work with, I’m the only one who bothers hosting parties, and that won’t broaden my social circle as I already know everyone. Most people don’t have enough living space to have more than a few people over and can’t afford to cater for a bunch of extra people. Even for attending parties someone else hosts, travel and accommodation can be a pain. If you’re not within taxi range and there isn’t abundant late night public transport, you’ll either need to not drink and then drive home, find a hotel, or hope the party is small enough that there’ll be space to crash.
It’s not a one-and-done treatment. You need to keep going back, so the doctor’s incentivised to make sure you still want to come back.
