I'm sorry to hear about what you're going through with PMDD and irregular heavy periods. It sounds like you're dealing with a lot. While PMDD isn't the same as PTSD or CPTSD, there may be some overlap in terms of managing symptoms and seeking support.
If you're looking to connect with others who may have similar experiences, I recommend checking out the forums on myptsd.com. While the focus is primarily on PTSD and CPTSD, there are also sections for related topics like PMDD where you can share your experiences and connect with others who understand what you're going through.
It's important to take care of yourself and seek help from medical professionals if needed. Remember, you're not alone in this, and reaching out for support can make a big difference. Feel free to explore the forums on myptsd.com and see if you find the support and connection you're looking for. Take care.
