Great questions! If your thoughts are accurate, no need to modify them. Then the task is to deal with things as they are. For example, if my thought is, "I don't have many friends," and that's a true thought, then I could work toward developing more friendships (rather than doing something silly like trying to convince myself I have more friends than I actually have).

And with scheduling activities, it's a common issue that with depression things just aren't as appealing or fun anymore. That is often the case when we start "behavioral activation," one of the most helpful treatments for depression. We generally start small so the activities don't feel overwhelming, and do things that at least in the past were enjoyable and/or worthwhile. Thankfully as we start doing more activities that support the kind of life we want to have, we usually start to get more out of them.
