Depression alongwith aggravated OCD makes one feel hyper-alert while having no energy to be alert about anything. One has no desire to know anything anymore yet stays busy to correct something which one doesn’t even know what is wrong or the wrong which actually doesn’t exist.
Why would you count things, literally every single little thing as little as your breathing, to correct something that has nothing to do with it?? What would you correct that isn’t even wrong in the first place??
The anticipation of something to go wrong is the reason behind OCD; something that someone holds very dearly or important in one’s life, and if that thing has gone wrong multiple times in the past, then the person becomes extra cautious or obsessed or say moves into hyper-mode of anxiety about it. It’s frustrating and utterly exhausting, both mentally and physically.
Don’t tell me meditation n shit helps in this. It is a problem of rationalizing irrational thoughts and attaching irrational behaviour (compulsions) to those irrational thoughts by somehow rationalizing them after observing patterns between them.
Add depression to it; And you have enormous amount of inner conflict while you have no energy or desire to even do the bare minimum of daily life, and sometimes even breathing and staying awake feels like a burden to the mind.
