I’m a type 2 so not exactly what you’re asking, I also have asthma and I’m a few years older than you, I am double jabbed (second dose was 24th April).
I have been taking all precautions I can throughout the pandemic but still got ill on 8th July and tested positive the following day. I have suffered mild fever, runny nose, hacking cough, fatigue and I’ve lost my sense of smell. I will be continuing to wear a mask in crowded spaces from 19th (well 20th actually as that’s when my self isolation ends) and I don’t care if I’m ridiculed. I will use a three layer fabric mask with a five layer filter insert, which I believe gives more protection to the wearer as well as those around them.
