for the past 22 years? That is wonderful. I'm sure by now you have established your daily practice. Those wonderful days on end of solitude is your retreat and by taking this wonderful advantage time, you can really open yourself to your true Buddha nature.
I study and practice the 59 Lojongs as a guide to life. Right now I'm working on maintaining a joyful mind even though through great stupidity I literally lost a sum of money. I could despair because of the loss, but I am taking it as a life lesson instead.
I guess what I'm saying is don't despair over human relationships. We have all been each other's mother throughout the eons of our samsaric existence. Take those feeling of loss and loneliness and breathe them in deeply and hold them, knowing that every single sentient being on this planet has those same feelings, and then breathe out all the love and caring and nurturing feelings to all of them who are just like you (are even you in reality) and give them the comfort and nourishment that you crave and you will feel your loneliness and despair dissipate.
