+1 to this. March for me will be one year and if I would have known the effects beforehand, I would have done so much sooner.
What I would like to add is have purposeful time off. Reconnect with friends and family. Do all the things that you have not been able to for the first couple of months. Read, exercise, laugh, cry, meditate, but most importantly LEARN. Make it a habit to get into the thought process of learning so you are intrigued again. Once you start to become curious again, you won't NEED to be motivated externally anymore, you will just be motivated internally.
Most importantly, if you can, go and talk with someone, either a mental health professional or a friend that will keep it 100%. Once I got full control over my emotions and how they were affecting me, it is as if I unlocked a superpower. Knowing how to cope and deal with the day to day stresses of life and not having to be feel bad or compare has been so you relieving you have no idea. I have gotten better sleep and am way happier than ever before. If you are not dating, I highly encourage dating just to date. Go in with no expectations, and be fully transparent about your intentions. Having someone to spend time with through part of your journey can also be beneficial. Obviously everyone's mileage will vary, I wish you well. Also, take some time away from electronic devices and try and do things with a purpose and do other things without it. Go and read to just read, go for a walk, just to walk. The entire process/purpose of a sabbatical is to recharge your batteries, reevaluate, assess , relax and plan for the future.
Best of luck!!
