What have you done to get through this?
What a brilliant question!
In no particular order...
Walking - long walks.  Sometimes w/music blaring in my ear buds, sometimes with an audiobook, sometimes with silence
Rekindle old hobbies - w/me it is crochet.  I've made many hats/scarves/blankets I donate to cold weather shelters plus I get to stab something with a stick and twist    
  
Try new things - I've gone to a few book signings and meet/greets with my favorite authors.  By myself because I am awesome company
Retail therapy on a budget - sometimes a new lipgloss or pair of sparkly undies boosts my mood exponentially (figure out what that equates to in dude land)
Take myself on coffee dates - slowly sipping and savoring each drop while imagine it refilling my sanity
Kayaking - in warm weather it is amazing and oh so peaceful
IC - I found a good one and while I don't go often these days, I do when necessary and mentally treat it as I would any other form of self care
Brunch with friends - sometimes I just ask a few friendly acquaintances if they want to go.  Sometimes it is a group and I find myself having a good time.  Sometimes it doesn't work and that OK - if I want to go I still do 
Turn in to your faith - and that doesn't have to be limited to religion.   Whatever you have faith in [be it God, the Universe, meditation, nature, etc.] go spend time with/in it.
Volunteer - find something that interests you and give a few hours of time.  Could be a local animal shelter, faith based program or through scouting.   Local libraries and community groups usually have a good line on who may need what.   Great way not to be alone, do something worthwhile and maybe just meet some new people.
Coming here and posing the question was a good start.   Please check back with us and let us know what you have tried and how it has worked for you.
