@esikora I respectfully disagree with your statement that those of us may not know what it feels like, but offer good advice. I, for one, do indeed know what it feels like, I have been there.

Feelings of depression and not having any desire can come on at any age, for any number of reasons. To reach out like @carrotbunny has done, is a step in the right direction. @celia16 has given some awesome ideas, that probably comes from their own experience or that of a family member.

Depression is different for everyone. It is not possible to know what another person has gone through from one post. Over the years, I have heard responses such as, "It could be worse," " Just don't feel that way" or other comments from people who don't want to listen or face their own feelings. I've learned to ignore those comments. But the good advice from the people in this conversation is helpful.
