Maybe the book will not help the OP, maybe it can. I apologize if it will not be of help to OP and hope that the rest of my initial comment can make up for it. Maybe I shouldn't have recommended books after suggesting them to take action (any action) and then immediately suggested them to read books (which can procastinate taking actions)

The book to me, has changed my actions and I consider it one of the action books. The question of for better or for worse is subjective and I believe it has been good for me but I concede that it could perhaps be bad for someone else or moreso that perhaps it might not be extremely relevant to OP. I can only guess.

I realized it after writing the comment but I do sincerely hope that OP takes what he wants the best from all the comments and basically does action. My whole comment is about taking actions, any actions specifically suggesting that more knowledge might not be the thing that they should necessarily want at this point but rather taking actions!

(I think it could very well be that when I suggested the books, it was me suggesting all the books which helped me conclude to the things said in my comment) but once again, it's not knowledge that's the issue but rather taking actions.

Now coming to the point about OP:

But TLDR, I once again recommend the OP to take actions and follow the advice of action.

Dear OP, the only thing you need to do is now take actions. That is worth more helpful to you than any book at this moment. I recommend reading these books later if you wish or if you don't then that's completely fine as well. I just hope that you can take actions to help your own life. You have to step up and realize the effortlessness when viewing from the bird's eyes view of a lifetime. It feels effort now but it takes more effort over a lifetime to maintain that lifestyle and coping up with the stress that it can cause than taking the struggle of fixing it once. I assume You had your job and everything going close to perfect once, have some leap of faith of confidence within yourself that you can do it again, that you have the capabilities to do so and you are capable enough and have enough strength, or more so find the ability to find strength within yourself. The strength is already within you (you are capable enough), all you need to do is look inwards and realize it again.

A lot of words which mean nothing except saying that an internet stranger wants you to succeed and to re-find the strength within you that you think has been lost. Take small steps as they go a long way. Thank you very much.
