Your post is quite wise. "'Cause not having any friends puts pressure on the relationahip with your S, for expecting it to provide more that perhaps it can reasonably withstand." This, I feel, is a very important point.
My H and I do have some mutual friends, however, I think that it would be in my best interest to have a friend or two of my own. This is something that I hope to accomplish within the next 12 months.
Perhaps I will be fortunate enough to meet someone from school who I can connect with, someone I can talk to openly. I do have my counselor, but she cannot socialize with me in the same way that a friend would.
I think that I shall list this as one of my goals for this year.
