Another option would be to leave the 121 for now and go 135 and build a bit of a track record of successful rides.
Piston or turboprop.
There are many jobs out there.
Build up 'pro' ride experience then go back 121 in 2-3 years.
A buddy in a previous lifetime had test anxiety to such an extent that he never went further then his Private.
Despite the fact he wanted to be a pro pilot for years and years.
Ended up as a mechanical engineer.
If it's any consolation, I hate taking rides also.
But I've learned to live with them.
