I have taken a 6 month break before going back to t, at first I was relieved to be on a break because my head was exhausted from all the self analyzing and observing patterns etc. As soon as I took a break I noticed my old self returning and the patterns coming back and I got back with my ex probably because I missed the intimacy and wasn't doing great.
So in a way the break was good because I was able to get on with my life again in a normal way(not obsessing about therapy) but in another way I fell apart. I would thing long and hard about taking another break until I know I am stable and able to cope with my emotions on my own.
I can relate to those feelings you are experiencing especially the exhaustion and only you know what is best for you. If you are feeling like you are in a therapy burnout a break can be great and really tell you where you are in your self healing
