Depression can be scary for those who are wanting to help you, and they might worry if you don’t get help soon, or don’t do anything that you will just stay there forever. And it’s definitely possible that you will stay there if you don’t allow yourself to move through the depression and to be in it when it’s there, but then to take steps to get out of it if it doesn’t lift for you when you allow yourself to be there.
The key to this is fully allowing yourself to be there without judgment. Allowing yourself to feel apathy. Feeling the disinterest, that you just don’t care anymore. And be there, knowing that this doesn’t last forever and that this is a part of grief.
