Do you think you have clinical depression?
If you have symptoms of depression, don’t take it lightly: get support without delay. You have the right to feel better and you will feel better. Confiding in someone you trust will help at first, but think about also including a professional who can give you an accurate diagnosis and help you find the right solutions for you. That could involve light therapy sessions, meetings with a psychotherapist, or taking antidepressants.
The important thing is to give yourself time to get out of it. Depression doesn’t disappear in a day or two. But one thing is clear: it can be treated! Hang on.
