Also, it sounds like you're not only looking for a quick fix, so you may want to evaluate your priorities and invest some time in these things to meet that deep emotional deficit for the long term- relationships take time, no matter whether volunteering or otherwise... just like we pay our therapists.... those other places to get hugs typically involve some type of exchange/commitment too, maybe you can look forward to an option like that once your busy days are over. Think of it like therapy- you have to schedule time for that- it's worth scheduling in some other time too it sounds like.
