so mine is kind of situational, but while I have a really hard time taking care of myself, I'm always able to get up and do things for my dogs. they need to be let out, shown affection (which is also good for depression!), fed, etc. it helps that they like to lay in bed with me and are very forgiving when it comes to timing on, say, when they're fed.

honestly I just think having something to care for in these situations can be very helpful, but it also depends on the person.
