Perhaps consider staying home for the next meeting or two. Go to bed early (or sleep in). Get some rest. Go for a walk - a long walk.
Definitely step aside for health reasons. Emotional health is as important as physical health. Being on medication is nothing to be ashamed of. (I was embarrassed, too, when I first started.) Don't be ashamed but also look to find what the cause of your depression is. Overwork could be one. Excess guilt could be a huge one. Feeling that you are earning 'conditional acceptance' may be another.
While in the org - towards the end of my pioneering days - I was starting to have suicidal ideations. I lived with that for about a year or two before seeking help. I was working full time to support myself and regular pioneering. I got to the point that I was crying alot. And either sleeping alot or not at all.
Once I started posting on JWD and started living my life the way I needed/wanted to live it and resolved my lingering WTS-induced guilt (from 'New Things Learned' on JWD and Freeminds!) I found I no longer needed medication.
Your mental and emotional health is critical to your overall health. Clearly, it will also affect your marriage, your childrens' emotional development and your parenting abilities.
I don't serve Jehovah, I serve the elders and the brothers and sisters at the Hall. They are the ones whose approval I covet.
I thought this was your most profound comment. With this statement alone, you know what you have to do.
Cruzanheart's response was oh so true! Covet the approval of your children and your wife. Without that, the other stuff is just a huge waste of time and effort.
The elders seem to be playing you - at every turn. It would be appropriate if you were angry with them for trivializing your responsibility to your family. The next time they or you want to meet, make it short. Say what you need to say and be out of there in 3-4 minutes. Excuse your self to get to your kids and then take off with one or all of them. (Maybe plan it ahead of time. Give your wife or the 5-yr-old a specific time when you will be there and honor that committment. If you want your children to respect you (and your requests to sit still-!!), honor your commitments to them. 3 minute elders meeting and leave.)
Think. Pray (if you still do). Take a good long walk. Sleep. Go play with the kids this weekend. I believe that the 'play time' will be more important and life-affirming than anything you may miss in service and meetings this weekend.
I wish you peace of mind and heart.
