You have my empathy on those issues. Remember to breath. I like to be very deliberate about breathing in energy, calm, vitality etc and imagine it as white light; then exhale all the stress and worries etc imagining that as blue smoke.
One thing you can do is nurture yourself with the most nutrient rich quality food and know you are taking good care of yourself to be able to better handle the challenges. I also like to 'walk it off' with a brisk walk where I can take in the sky, trees and feel the energy of nature balancing as that quiet time is taken.
I wish you wellness and patience to deal with your issues.
