Part of what can make implementing any of these aids more difficult is the resistance to accepting oneself as a "sensitive" or (perhaps more difficult) as a "fragile" person. These can be experienced as discouraging or demeaning terms. That's unfortunate, because that makes it more unlikely that you will take the next steps to help ameliorate these circumstances.
Think in terms of the idea of suspending judgment about yourself. If you can experiment with doing this, even a little, you will then be able to take a step forward toward self care. Don't expect an all-at-once solution. This is all on the order of step-by-step, over time. This of course implies the necessity of some discipline, some perseverance. Again we run into the effects of the industry of quick-fix propaganda, and the resistance to commitment.
But try, at least. Experiment. Have support for your efforts. Love yourself.
