GID aside, the loss of family and friends, especially arouond this time of year, is a tough one to overcome. The way I look at this loss is this:
If they cannot accept who you are, and support you, then how much of a friend were they really? There is an old saying "You are what you do, when it counts" and when our friends are in need, when they are at their lowest, is truly the time we as friends, need to rise up and support them.
I cannot vouch for family, for I have little to none, it was a decision made for me long time ago.
Friends are another matter. Making new ones, as we grow older, is increasingly difficult. I have joined a couple of clubs, one being a photography group, and have found new people to talk with and hang around with. This has helped.
And while we cannot be with you in person, know that we *fully* support you in spirit, online here, and in our thoughts. You are stronger than this, rise above and defeat your doubts (sorry, that came off like a Jedi saying, you get my meaning)
