Hi there, I'm pleased you replied. Sorry that I did not reply more quickly - my sleep cycle is really messed up all of a sudden due to the flu.

I'm not really familiar with the conventions of ashrams, however, I do wonder whether there is a midpoint you can reach which maintains respect to your Guru - some kind of a local group which holds meetings but it not an enclosed community, per se, where there may be people who lead the kind of lifestyle that you do? It might well be worth exploring. It really is important to feel accepted and understand, that you share interests with those close to you.
Do you live in a city? I'm willing to bet there's places that put on music events suited to your tastes. You could try to meet someone online who shares your interests and go with them to an event - there are phone apps and websites which can bring you together with people. No expectations set - there are so many isolated people in this world - you could be the one to help one of them.

That said, I would encourage you to try out engaging in the activities which the people around you like. You never know, you may enjoy them more than you realise, and the effort in striking out of your comfort zone to meet them half way could work wonders in breaking down that invisible barrier which you and they can sense.

What's most important is you focus on the here and now, though, care for yourself like you would a loved one. Our minds and bodies have the most phenomenal power to restore themselves provided with the right nourishment, and with time.
