Hey SoccerGuy,
I'm in the process of going through a separation myself. I (we) haven't been really happy for a long long time. I always wondered why I was so very lonely in the marriage, so now, it almost feels like a weight has been lifted off my shoulders... that's probably why I'm not too brokenhearted about separating.

Two things specifically have helped me A LOT: Support groups and hobbies.

You may consider finding a support group of others going thru similar situations.. I've met some great non-judgmental people that really listen and understand.

One more very important thing for me is my new hobby. I had ZERO experience with but now love greatly: vegetable gardening. I started with a small patch of cucumbers and radishes two years ago, but now, I've created more space and have added tomatoes, onions, peppers, garlic, herbs, beets, etc... For me, it feels very spiritual to care for and watch a small seed grow to a flower, then a fruit. When I harvest and consume, it feels like a gift from our Earth.

It's not easy, I know... I hope you can find something (an old hobby or a new one) that fills you with joy!!!!! I wish you the best of luck!!!
