Hello AliMa, people can be told by other people and/or psychologists/doctors that meditation, exercise is a great way to start your journey to overcome how you are feeling, but not everyone can relate to this, I certainly didn't because I didn't want to do any exercise and when you feel like this, then how can you possibly do it.
With meditation and as I'm a non believer, I couldn't meditate, because to me, it's like praying for something that hasn't happened, and I know other people will disagree with me, so be it, but that's how I feel.
Being in a state where perfectionism means a great deal as it could indicate an illness that needs to be diagnosed by a doctor, as I'm not qualified to say so, but I would type that word in your search browser or perhaps the search bar at the top of this page.
Understanding perfectionism requires a plateau of different responses where some psychologists can cope with while others may not be trained in this particular area, as my last psych had no idea what it meant or why I should take any medication at all, I only had a few sessions with him because he just couldn't relate to what I was trying to say.
By your psych saying that you will know when it's the right time to go back, leaves a lot in between that needs to be discussed.
