What is happening if I needed a job yet afraid to start new again?

[Stitching]

I've been struggling with this fears for few months already, I am on a foreign country and I lost my job due to the pandemic so i've been sending my applications online but most of the time when my phone rings immediately panic attack and anxiety are hitting me thinking that it maybe a call for interview, It is always so bad that I felt I am going to have heart attack. I don't wanna felt it but I don't know how to fix, it is getting worst I tried to distract myself and telling that it is okay but it seems I am not ready yet, the consequence of losing funds for expenses without means are not threatening me or get worried with. I'm sure this is not normal, what am I supposed to do and what is this happening to me?

Thank you and I appreciate your responses.
