my suggestion is quit doing the drugs and alcohol that you have posted you were doing (weed/ cocaine/ meth....)

one thing you might not know is dissociative forgetfulness is different than things that even normal people forget like their meds, names, places diagnosis's ....especially if there are many meds, names, places, diagnosis's involved. dissociative forgetfulness is a special kind of forgetfulness and theres more involved then what you will find on the internet with your researching (incase you are back into researching again)

another suggestion when I cant remember things due to my physical and mental health problems I write things down. when its time to go to the doctors go through your medications and write down what they are and what the dosages are. (or you can just tell the treatment provider to look in their files. they will already have that list in your files)

suddenly not remembering family members names and getting worse comes with many physical health problems not dissociative problems. for this you will need to contact your treatment providers who can order some physical health tests like drug and alcohol testing, blood tests and more.

I dont know what else to tell you because every time your treatment providers get you stable and on track and on the right treatment plans you throw it off with things like quitting treatment, and doing drugs and alcohol... yes I know you will be able to come up with lots of reasons why you do this but the bottom line is if you want help then you need to do what your treatment providers want you to do, like stopping the drugs and alcohol, going into the hospital and letting them get you set up with the specialist they want you to see and follow through with letting them help you get your SSI.
