It helps me to participate in something that takes a lot of my mental and physical energy. Also, being among friends in a fun atmosphere is good.
Playing in bands is one of the things that totally takes me somewhere else. If it does that for you as well, this might not be a good time to set it aside.
I journal and vent there when I need to. It's also helpful for me to read the entries I made while we were still together. I did that last night while feeling a little emotional and was quickly reminded of why things are as they are now.
