I think it started when I almost got drowned while drinking water after eating then everytime I drink now, I'm scared because I might get drowned. Then months later, I was diagnosed with anxiety. I don't even know how, like I was normal today then the next day, suddenly I can't breathe. I thought my asthma came back. Then I went to the doctor,he said its anxiety but I don't believe it, so I went to another doctor and same diagnosis. After a month, I still can't breathe properly so I went for follow up check up, the doctor told me to get blood test for cbc, platelet count, FT4, TSH. If all turns out normal, I really am having anxiety.
