I think I can relate, at least somewhat. I live with my H and my elderly mom lives with us. Sometimes, my H is working a lot of hours and that leaves me with my mom. My H and my mom are wonderful people. I just end up feeling "alone" at times.
I have old friends, yet I have not felt up to meeting up with them. I have been in a deep depression and also have several medical conditions. I am an introvert by nature, which helps and I do crave and love my alone time. At the same time, there are times when I am a little lonely.
I have made friends here at PC and we can really relate. I enjoy my PC friends very much.
I hope you can find someone(s) with whom you can relate, either online or IRL.
