feeling fed up and doubting self and instincts.

[TGreaves]

recently had yet another admission in hospital where i was a resident of icu and hdu, my asthma still not fully controlled feel dreadful breathless esp on exercise, i coughing when walking certain distances waking for nebs my pf are 240 at home yet at gp this pm it was 190 then 320then 240 and sats were good at 98 i now feel like a fraud as what I'm feel in isn't the same as my readings. dr put me on antibiotics as precaution but i del like a fraud and tempted to cancel my two consultant appointments as i looked like i was telling fibs when i saw him today. I'm classed as a severe brittle asthmatic yet one of my consultants think stress can be a trigger, i feel like things aren't real and i wasting time yet i so breathes and feel tight chested yet things are eased when nebs have been done. anyone else feel similar. i feel fed up as been unstable since august
