I have PTSD (for reasons not related to the A) and I have been in therapy but am just now able to open up to my therapist about the trauma. It is very real, your body reacts, the nightmares, panic attacks... I get it. It is hard to explain to people what it is like but don't be discouraged if someone dismisses how you are feeling. It is a very real thing.
It takes time to work through it and yes, self love is key. To know that you are NOT in that situation anymore, stronger and out of harms way. But it does take time. You aren't alone. I developed little tricks to cope when I feel a memory coming on. Do whatever it takes to stay in the moment.
It will get better.
