Hi, Shaye. I'm glad you found us. Welcome.
What is HSP?
"Probably have the PTSD in a way" is a good start to move into therapy or some sort of professional help. Self-diagnosing is dangerous, and I encourage you to gain an appropriate diagnosis from a professional. Hopefully, you do not have PTSD. That in no way means your suffering, feelings, and issues are not valid. It just means your brain may not be irreparably damaged from trauma. I hope it is not.
Regardless, hopefully you will find some good resources and tools here while you seek a professional and sort out your diagnosis and current issues.
