Recurring CSR in right eye. For this?

I have recurrent CSR in my right eye & have undergone focal laser multiple times over last few years to stop the leak. However the leak starts again in a different spot after a while. I am aware that one of the main cause for CSR is stress - however, I have very less stress & this was also reflected in cortisol test that my doctor asked me to undergo couple of years ago. Currently I  have CSR again in right eye  & this time the fluid accumulated has increased after focal laser which was done in September after FFA & then again in November . As per doctor, PDT may be required as leak seems to be in fovea per recent FFA. I am a diabetic type 1 &  do not take any medication or use any products that may have steroids. I have no clue why this problem seems to recur so often. Is there any way I can prevent this from recurring? Is PDT the only solution for the current fluid accumulation.  Also are there any alternative therapies available for this? Any advice  will be very helpful.
