make yourself sorry you are going through a rough time. I had depression for years as a young pioneer, I know how terrible it is. Not helped by the Watchtower making out I was spiritually sick and telling me not to take antidepressants because they are addictive. Go and help someone else to take your mind of it or do some hard physical work they said.
They don't know what they're talking about. There is more than one cause of depression. For me it was caused by both a physical illness called systemic candidiasis which affects the brain chemistry and stress from working my butt off pioneering depleted a neurotransmitter in my brain called serotonin. Prolonged stress depletes serotonin. There is also some evidence that some people are born with lower levels of serotonin in their brain to start with, then if you pile on the stress your brain can't function properly.
The way I dealt with it was to cut out all unnecessary stress in my life. Obviously there are some responsibilities we have to take care of but other than that pull back, learn to say no to things. As a short term remedy I have taken SSRI medication to build up my serotonin. They do work but you can also build up your serotonin yourself with rest and reducing stress.
Learn to do things to make yourself happy and don't let JW ingrained guilt make you feel you always have to be working. As others have said avoid negative people who drag you down. When you are feeling really bad just live in the present completely. Don't think about tomorrow that just stresses you. Deal with now, this moment. Living in the now really works but it takes practise. Hope you feel a little better soon. Take care.
