That's a great observation, Jake. As JWs we were told we could never trust our thoughts or feelings, that they were always sinful. When you are told that for years, you become divorced from them, and rather than dealing with your emotions and listening to your instincts, you become disconnected from them and issues get suppressed and ignored, and can surge to the surface as cog diss, depression, physical ailments and other things. If you are told your thoughts cannot be trusted, that what you think about or feel about things is wrong unless it's a certain way ("Are we not grateful for the Faithful and Discreet Slave? Do our hearts not swell with joy when we come to the Kingdom Hall? Are we not appreciative of all Jehovah has done for us" and so on, telling us all the time how we should feel) is bound to make you doubt who you are, lose confidence in who you are, and feel guilty over who you are.
And then of course, "do more, Can you organise your affairs to pioneer? Can you adjust your schedule to spend more time in the ministry? Do more!" tells you that you are never doing enough. Combine that with doubt of your own sentience, you are gonna end up depressed and miserable. I struggled with it for years, and was always saying to the elders, "Woe is me, I'm doing all I can, and yet they're asking for more! I feel so bad." And they'd say I was doing fine, but on an on and on at every assembly, WT and meeting, "Can YOU do more? Can YOU cut back on work? Can YOU save more lives? There is no reason for not being able to start Bible studies," they'd squeeze, and squeeze and squeeze, and tell you that you should be happy while they're doing it.
