Hmmm--tips on setting small goals--you can go as small as getting out of bed in the morning and then showered or washed up and getting dressed.
Really don't know where you want to begin.
When we had to set "small goals" it was basically daily needs then moved on to doing some activity during the day. Goals jumped around alot for awhile.

Even now, we have goals that require us to do things like limit computer use, let others share time either as a day or half day or by the hours....., do something for myself which might be reading or napping......

staying grounded in the midst of things is tough......there are some sites which talk about grounding skills--one here i think. check it out for ideas.

keep living your life as best as you can. one foot in front of the other. small steps. you may need to sit down and rest a bit, or re evaluate what needs to be done....for us having a bit of "normal routine" helps keep us grounded. same time waking up, going to bed, eating etc.....

By the way, there is a DBT chat here also--check the calander for info on it. Might get you in the right direction while you wait.
