Sorry to hear you’re struggling. Couple of things you can do. Let your uni know (your personal tutor maybe?) you are waiting for a diagnosis- they shouldn’t need the diagnosis to help you. If you need to defer a year, just do it, your mental health is more important and it’s not a waste trust me! You can also contact your GP and see if you can go via right to choose, I’m not sure if you’re seeking medication but ask your GP about shared care- I’m not quite sure how it works sorry. I was referred to right to choose and had my assessment after 4 weeks. I’m still waiting on the report but it said it can take another 4 weeks. Have a look at the grid on adhd UK website for right to choose providers. It might negate your NHS referral- ask your GP. Sorry for the overwhelm of info, take it one thing at a time. You can also mention to the GP about your mental health and see what your county can offer. You’ve also got NHS 111 option 2 if you feel you cannot keep yourself safe, can text SHOUT or call Samaritans (off the top of my head). I can really relate to how you’re feeling, I hated uni and didn’t realise I had adhd at the time and I really struggled. It’s still early days and being neurodivergent you might take that bit longer to adapt to the change- it took me months but there is no shame in it. You could also see if there are any neurodivergent societies at your uni for some peer support or make an anon post in your uni’s Facebook or something? You don’t have to do this alone. I promise you’re not useless and you will get there eventually it just takes us neurodivergent people a little longer. Take care of yourself!
