I think your right about the depression.. I definately feel better when the weather is nice.. which is 1/4 of the time our of 365 days .. I am somewhat of a hermit.. and do not frequent coffee shops.. just the gym and work.
I have read to go to a coffee shop to meet people.. dont agree that is the best place and neither is a bar. coz you get people that dont care about their health as much.
I am older though.. and dont look for a place to meet people as much as when I was younger and loved to party.!! Always met people then. !!
And I think dating with people at work is asking for trouble so wouldnt consider that..
I think Washington has a lot of possibilities.. if someone really wants to know you they will be bold and let you know.. I have met people at the store that have asked me out to dinner !! Rare, but I think whereever you go .. church, outdoor functions.. the parade on the 4th of july, the library, the store, the outdoor fruit stands and like where I live in Edmonds they have Farmers market in the main street on weekends in the summer.. you can meet people where you go.
It is soley up to you..
I am pretty much as you say a hermit.. but plan on getting out more..
I just think eventually the universe will hook you up !!
