Hey!
I'm really glad you went to seek help from your GP, three years is a long time! It's horrible feeling like this with Uni on top of everything, definitely adds to the stress of life - hopefully your Uni are helpful if you are struggling, especially in terms of deadlines as it can be so hard to get everything done.
It seems as though writing notes would be a really good idea, I usually avoid Drs because I'm not too great with them in general so when I get there I probably would just forget absolutely everything.
You're definitely right though, putting it off is probably the worst thing to do - thank you for your advice and support and I'm glad you are now getting the help you deserve! xxx
