Is it worth seeking a medical diagnosis if I have an educational diagnosis of autism?

Hey folks, 

I'm a uni student who has an educational diagnosis of autism which enables me to access some reasonable adjustments to help with my studies, however, I am currently considering pursuing a formal diagnosis for autism through the NHS to access more support. I currently cannot access disabled students allowance for example since my diagnosis is not 'formal'. 

Even with the support from my uni and the reasonable adjustments I find that studying takes a toll on my physical and mental wellbeing and so was wondering if any uni grads or current students who've been in a similar situation have any recommendations or advice that could help me decide whether its worth it or not. 

Thanks in advance!
