Living with CPTSD, Chronic Pain, and Social Anxiety

I believe that a long history of child neglect, narcissistic abuse and physical abuse have caused CPTSD which has led to other symptoms like chronic pain in my upper back and neck which seems to worsen with stress (there is no physical cause for this pain) and worsening symptoms of other conditions I have such as anxiety and tinnitus which seem to both worsen the other. Because of the neglect alone I have lived a mostly internal existence with small durations of coming outside myself to talk and interact with people with out it feeling synthetic or cyborg like but the energy or courage to do this never lasts more than a few weeks and then I go back to my usual cold self whom nobody likes and who likes no one. Months or even years can go by before I have the energy or courage to come out again and be with others in a way that feels REAL to me. I’ll still socialize but even the other person can tell I’m not “myself” and the anxiety is too much for met to bother with so friend’s are easy to come by when I’m in this mode but hard to maintain once it wears off. I do not think I have bipolar tho as my rises in energy are usually do to external causes. Like leaving an oppressing job might lift my spirits enough to be a rockstar for a few weeks my chronic pain and tinnitus even lesson or vanish but this almost never happens just on its own.
