Can't really comment on the relationship void, I can be a love addict in that area and now gone completely the other way. Aside from toying with going back to my childs father a couple years ago, I've been celibate for a long azz time. I'm now an avoidant. I hope to work on this (and other issues) doing the steps (when I find a sponsor).
I am in your shoes regarding school though. I went back 4 months ago and I am finding it really tough. Infact, I kinda want to throw in the towel. Following your thread with interest.
