I had Asthma in my childhood n it's back

I am 28years old, moved to Bangalore about a year back. I was diagnosed with  Acute Urticaria in July 2017. It was in control when I took medicines. I noticed my Asthma slowly started this May or June 2018 n I'm getting very frequent episodes. It's triggering at slightest dusty areas or even if AC in office or home is turned off. It triggers if I laugh(I generally used to laugh frequently but have to think now), it triggers with sneezes as well or if I try to talk fast. I tried Checking my diet as I used to have heartburn frequently n even that is  triggering asthma. I use Asthalin n I take that if I feel it's severe. From a week or 2 I'm unable to sleep more than 3hours n I wake up due to breathlessness. Please let me know if there's a cure to this as I see my health deteriorating slowly. Thanks in advance. Suman
