Sounds like a fine plan to me!
I do not have a clear diagnosis date but noting your diaversary and celebrating getting better can't be wrong
Have a good one!
It's my 1 year dia-versary today, and I am enjoying a glass of wine this eve. Not exactly celebrating, but recognising that diagnosis turned my life around. Ditched 3 stone and HBA1C from 69 to 28 and feel great! My diagnosis was genuinely a blessing in disguise. Go on, treat yourself x
