Thank you all for replying. The day after I posted I spent some time at the beach with a good friend and that was wonderful. I am now back at work and it's been okay. I would like to change jobs but am going traveling this year do need to hang on to the one I have!

I am feeling a lot better. Spending a lot of time alone is certainly a trigger for me. I have some social things coming up which will be good. As for dating - I'm a bit old fashioned! I like to meet people face to face, but it seems that Internet dating is the way to go. We'll see I guess. I haven't been with anyone for three years, so I'm rather rusty. Thanks again to all of you.
