So bit of back story for context. When I was 17 I was admitted to ICU as a result of a life threatening asthma attack. The attack was brought on by own immature stupidity - being young and invincible smoking on a night out seemed like a great idea, and the this triggered my (previously very mild) asthma, resulting in a 3 week long hospital stay, 5 days of which were spent in a coma in ICU. I have never smoked since and never had a hospital admission since, although do have worsening symptoms and flare ups in winter. I'm now 33.
Since then my mum has been, understandably, over protective. I moved out of her home 10 years ago and still receive phonecalls twice daily, with texts in between to check I've taken my inhalers, not been wheezing, etc etc. She never calls to chat a out any other aspect of my life, or her grandchildren, every conversation is about my asthma/treatment. I've tried on so many occasions to tell her this isn't necessary and that I'm more than capable of looking after myself. Her response is always refering back to the ICU stay, and how I could've died and didn't understand what I put her through.
This week things escalated to a whole new level, and she actually contacted my GP and arranged an appointment for me because she thinks I need seen - asthma has been slightly worse than usual due to have a respiratory illness, but nothing I'm concerned about and definitely do not need to see a GP. I have obviously cancelled the appointment and apologised to the surgery. I'm also a paramedic and more than capable of managing my condition independently, and generally have minimal input from the GP/asthma team - all appointments are by phone and usually only once a year.
I'm actually getting to the point where I'm considering cutting contact altogether because she's so overbearing. I do understand her concerns and try to reassure her but at the same time, I have a life to live and this does not resolve around my asthma.
Any suggestions on how to approach this behaviour before I lose it completely?
