Think mines could be hypervigilance as well. I am so sick of being aware (beware!!!) of minuscule sensations in my body when I am very relaxed, either sitting with company, watching TV or not particularly doing anything. All of a sudden my mind brings my attention to the sensations - heavy weight in my arm, then tingles (usually the left arm) and it starts to be this doctor inside my brain telling me it's something serious with my heart! Of course, this can set of anxiety in me and start panicking! Or the tingly sensations I can get in my face, around the lips! Sometimes this crushing feeling in my heart, like it's in a vice and being squashed (had it checked it out, I am seemingly very healthy with good heart health, go figure!) then this pain can turn into my rib cage cuddling into my body, crushing my organs (this is a scary symptom!) So yeah, I think it's my awareness and attention on my body so much and always concerned with it. I just can't seem to forget about it.
Not like the way I use to when I was a kid. If I fell off a swing and split my head, or the time I fell off my bike and skinned my knees badly. . . soon as it was seen to I would be back out playing with my sweets with not a care in the world. Even the time I was given penicillin and my throat swelled up (how I found out I was allergic to it) and even then this didn't scare me!!! But now? Everything scares me, every twinge, every sensations, every ache. . . constant questioning, oh-no, what's that? Something is wrong, the doctor's have misdiagnosed me, etc. . . it's endless and it's exhausting.
Tried CBT but that worked a little. . . because the more I challenge thoughts, the more my brain challenges my challenges lol.
There is a part of me though that is just floating! Been reading a lot of books by Claire Weekes, how she states that we should just allow ourselves to feel whatever we feel, without the story telling, without analysing, questions, trying to fix, trying to make better. Helps a little, not all the time! So, I would say plenty of researching, educating myself as much as I can with books, the web (staying clear of symptoms checkers, obviously lol) about PTSD, c-PTSD, anxiety, panic disorders, depression. . . started reading about buddhism, zen, mindfulness. . . this can help a little too (sometimes). Just never giving up and learn more about it, re-learn and being on sites like this helps too, especially feeling I am not alone and that brings a connection I need too! :)
