job hunt anxieties

i have been unemployed for a couple of months now and today i got too motivated and applied to too many openings. i didn't think much about it but a few hours later I received messages from a couple of recruiters. Applying for the job was easy but actually interacting with the recruiters is making me too anxious. one of the recruiters called me on linkedin just now and I freaked out and didn't pick up the call. i'm guessing i'm not getting any calls from that firm anymore.

Is this normal or is it just me??? I kept postponing applying for the jobs because of the same reason. Now I gathered the courage to apply but still can't go beyond apply phase due to my anxiety. What do i do?
