Well I did have mental struggles with anxiety and depression pre rsd and with it well it is bad right now again. I have had enough therapy and treatment pre and after the rsd to write the book yet it is hard to apply sometimes if that makes sense.
With the rsd it gets confusing for me what should be true fears and what becomes irrational. In any regards I really am working on staying in the day. I am a worrier of the future and regardless of what may or may not happen it does not help me in the now. When I am going through a time where panic is so high I try to self talk and do deep breathing I learned in my biofeedback. Also use the support of others by calling someone. For me my panic at times can be a build up of things that I did not process in an appropriate way at the time. So trying to not let things build up is important. If you are starting to feel depressed,anxious,etc trying to face it at the time and work on ways to help relieve some of it.
As for doing things that are normal in life but feeling overwhelmed I feel the same. So for me making small goals and trying to make set plans which can be flexible but also give a road map for the day or things that need to be accomplished can feel less scary.
Trust me I know this is all easier said then done. Really I should be the last one giving advice since I don't take it often but just trying to pass on what I have learned. Sending peaceful thoughts to all
