Hey, Erin <3
I wish i knew anything or anyone that could help.
I can only imagine the mental strain this is beginning to have on you. I know not much is accomplished but i suggest ringing a mental health helpline and talking things through, keep putting your thoughts and worries out in the open so its not swirling around in your mind, sometimes they might have some steps you can follow, or help you find ways to get more insight to your condition and what you are currently experiencing. I'm not sure how things are done in another country, where are you from?
Where you are mentioning rehab, if you think they arn't taking you seriously, you can find some community help as well, I'm sorry I'm being vague but not sure how things are done where you are. I suggest, pain relief and spending time with a special friend or family. Deep breath, you are strong xx If you like, you can message me and i can ask someone experiencing MS what they reckon
