Many, many times, when I have been severely depressed or anxious, I have heard the repeated suggestion that I just “get out and do something”. I think this is a common misunderstanding that people have about depression and anxiety, that the cure is always just going out and finding something to do.
Personally, I can say that if I am mildly or moderately depressed or anxious, getting out can indeed be a huge help. It is a good way to distract myself and can make my life feel less empty and more meaningful.
However, if I am severely depressed or anxious, “getting out” is absolutely NOT the answer, and I know this from experience. Whenever I have been severely depressed and I somehow managed to make myself leave the house, I have just been a teary, numb mess who ends up feeling worse for being unable to stop the tears in public. During these times, I am unable to join in with anything going on around me and will just sit there and cry and feel embarrassed, wishing desperately I had never left home.
As for times of severe anxiety, I often also deal with severe irritability and a tendency to snap at others, even when I don’t mean to do so. “Going out” when in this state can actually damage relationships because people wonder why you are taking it out on them, even if you absolutely don’t intend to do so. Not to mention the fact that severe anxiety often comes with intense panic attacks, which are something that is horrible to experience in public. Panic attacks suck no matter where you are when you have them, but given the choice I would always choose to be in the comfort of my own home dealing with one rather than out in an unpredictable public environment.
