Yes, healing from severe trauma here and the brain is an amazing machine. Everything you said sounds familiar and I can tell you that EMDR can help you process what's hidden to minimize or even get rid of that unexplained anxiety. I learned about mine in regular talk therapy over a silly breakup and ended up getting transferred to a trauma team after stuff started to come out. I was later diagnosed with DID and that treatment helped me recover some memories and get rid of the crippling anxiety (#3) that came with it. I would highly suggest exploring this avenue with a therapist you feel safe with. That can also help with your #2 issue above which sounds like a bonding issue (very normal with abused kids). As for the cancer, it is absolutely a possibility, which may get some relief from trauma therapy. I'm almost completely healed, no more eating disorders, crippling anxiety, nervousness around men, etc. EMDR and CBT is magic. Best wishes for your recovery.
