I think about my family too, Fluffy, and have the same feelings about being trapped and hopeless. Whenever I think "screw them!" is time to start to worry and usually when I go IP.

We have a scenic highway here called the Kancamagus. When I start to feel SI coming in I drive it and spend time at all the stops to remind myself there is still beauty in life. If I have time I'll do a short hike off of it or go swmming.

If it gets to the point I can't be alone, I'll give someone my meds and keys. A few years back we actually flipped the doorknob on the bathroom around so I can't lock myself in it.
