Yesterday I Ended Up Having A Asthma Attack And Panic

Yesterday I ended up having a asthma attack and panic attack at the same time, i was struggling to breathe, hyperventilating, headache, fatigue, dizziness, could barely move due to weakness. Went to gp and got nebulizer and it did heaps, waited 10mins and I went downhill again, chest hurt so they gave me 4 puffs of inhaler. At this point I was becoming less and less responsive, couldn't keep my eyes open and became quite weak.they gave me another nebulizer to try and clear back up. Got so bad I was in and out of conciousness so went to emergency via ambulance. When I got there I did all sorts of tests and was still quite hard to talk to. They said I have a respiratory infection which doesn't go well with asthma. After 5 hours of being at home I had to go back to emergency due to hyperventilating and couldn't breathe, couldn't get it back to normal, shakes, tingles, headache, weakness, I was in and out of conciousness again and non responsive. At one stage I fell asleep and when I woke up I thought I was at home.
They sent me home after telling me it was anxiety.
Is it all matching up because none of this is making sense to me
