How to De-Stress! Help!!!

So I’ve been trying to conceive on and off for a year now. Had a miscarriage in February.

Started trying again between April to August and stopped as I was finding the process too stressful.

I feel I’m doing everything I can - good diet,exercise, sleeping well, staying hydrated, taking Vitamins, Husband is taking vitamins and doing stuff for sperm health. The one thing I can’t seem to do is manage stress. I think itsprobably the thing thats stopping me conceiving. Anyone any tips/advice on how to de-stress?
