You CAN do this, and you WILL. Like Gardener says, use your current issues as the catalyst to push you to step outside your normal, safe existence, and try new things, do new things. Experience life.
I know in my case, I had shut off so many things around me because they were different or I was "too old" to do those things or I couldn't b/c M'd people didn't do those things. Well, I have reacquainted myself through this awful process with what it means to be alive. And I don't ever plan on leaving that again.
