OK, they've arrived and I tried them for the club training last night. Very nice.
Much thinner and lighter than the Nike Dri-fit ones I usually get. Therefore a lot more easy to forget you're wearing them. Plenty warm enough too. They aren't as warm as my usual ones at first, but retained the heat well, keeping my legs nice and warm whenever we stopped.
Not sure I'd wear them without shorts over the top as they really are tights more than leggings (if you see what I mean).
The Medium was a nice fit and bears a pretty close comparison to what I usually get. I've never tried compression gear, but these seem tighter around my (skinny) calves in a way I quite liked.
I'm also in a very similar situation and have been for a few years. My wife has been clinically depressed for around ten years. About 8 years ago we moved to an area where we don't know anyone (for a fresh start!). It didn't really work and, whilst we do have good times, it can now be a lonely experience for me when my wife goes through periods when she really doesn't get out of bed much.
In those times I run because I have to. I realised a long time ago that it's one of the things that keep me going. Thinking about it, I have a number of alternative psychologies to motivate me to get out and do it.
Sometimes I feel good and giving and want to be the strong one. That's when it's easy. "I'm doing this for both of us".
There are also times when resentment creeps in. That's when I'm doing it for me. "Fuck you, I'm not coming down with you". A run generally brings me back to an equillibrium.
I have running so much part of my own personal therapy now that if I do feel dark moods decending, I go for a run almost out of fear of what might happen if I don't. The great thing is that it always works, at least to some extent. I don't know what I'd do if it ever failed.
I have no idea if this would help for you. All I know is exercise works well for both if us and now we even run together sometimes.
