I feel you. You remind me of myself to some degree. The thing is, there’s a certain degree to this that is largely outside of your control. We live in an increasingly atomized society where people live in a siloed existence. Your experience at bars is not unique in that the mindset of people in generally drifting towards the anti-social. If you tried meeting new people in these places, you would be viewed as a creep, so I wouldn’t even consider joining these group tables unless circumstance invites it. The advantage you have over 99% of the population however is that you are an occultist, so you have options to fix this.
Glas’yos from the EA’s book of Azazel has the ability to alleviate depression, anxiety, paranoia, and pretty much any psychological issue you may be having. That’ll help fix the you problem. In terms of the friends problem, Saspu, again from EA’s grimoire is a good bet. he is able to bring both love and friendship into those who call upon him. Calling him to help bring friends into your life will make things infinitely more easy for you. These spirits are not to be underestimated. If Asmodeus can arrange a threesome for someone without having to do much of anything, then they certainly can help you meet a few new friends. Take advantage of the knowledge in this place is my answer.
