I have been missing work and not doing anything I enjoy because I constantly feel like something bad is going to happen and I always feel like my throat is closing
You’re not alone I going through the same thing right now, just had to leave work I can’t focus.. had an bad panic attack Thursday and today was my first day going back n I still haven’t shook it and I constantly think something bad is gonna happen to me been feeling like this since 2010 it’s the worst 
going to see my doctor to get test ran and see if it’s anxiety etc. how long have you been feeling this way?
Just try and push through an do as many things as you possibly can, dont let the anxiety take over your life. I have suffered for 12 years and I cant stress the importance of doing as much as you possibly can.
See a doctor and get a referral for your local mental health clinic. There is people out there to help x
