I have complex PTSD from being abused by my ex husband. It manifests itself mostly in anxiety and hypervigilance. I am currently on a low dose of an anti anxiety medication which takes a bit of the edge off. The biggest this though is my therapy. My therapist has me practicing breathing techniques that really seem to help. 3 times a day I sit in a quiet space for 15 minutes. I breathe in for 4 seconds, hold it for 4 seconds and breathe out for 4 seconds. Before starting I make a list of the feelings that are plaguing me (ie. self judgement, fear, self doubt, etc.) then I list out the feelings that I want to invite in; acceptance in place of judgement, peace in place of fear, confidence in place of judgement. Once I feel connected with my breathing I go down the list individually and mentally ask for the negative to be released when I exhale and the positive to come into me when I inhale. So exhale the negative and inhale the positive. For me it is in the form of prayer as I am Christian but you could completely mold it to fit your own beliefs. It feels silly at first but over time, it helps to make you feel more at peace throughout your day. My goal is to manage everything completely with behavioral therapy and get off the meds by the end of next year.
