Difficulty breathing and choking feeling

Yesterday around 3 times in whole day I had sudden difficulty breathing and a choked feeling in throat or a feeling in throat that we get before we aree about to cry.. U had this feeling yesterday 3 times... The last one was 1am and it couldn't get rid of it for a long time...watched something entertaining online and got releived...and slept. Woke up in midnight...and then same shortness of breath and choking again and I myself know it's Anxiety. I have been suffering from it lately. And I was preferring to change my lifesttyle and sleep instead of taking medications.just the thing is that this difficulty breathing during day time and the feeling of choking it's scary for me and makes me worry more . My liver function test is normal , I haven't had fever in a long time till now. What should be next steps.
