I’m an AT (Assistive Technology) Trainer and I’ve been Type 1 myself for over 45 years. I frequently work with students who are Type 1 who have been awarded the DSA grant for the condition alone, or rather the impact it can have on a student eg Inability to concentrate during lectures etc. I strongly recommend that you go for the assessment as the support you can be awarded can make a significant difference to your studies and beyond. Good luck.
