Did you try IELTS? I don't know what you are using TOEFL for, to apply visa or to apply some sort of school, but I'm aware most accept both TOEFL and IELTS. I have taken both, and IELTS was much less time pressured. It is also helpful that you can sometimes take speaking part on separate day. I have anxiety and panic, but IELTS was much more manageable.

If you have to take TOEFL, maybe it can be helpful to be aware that you can take TOEFL as may times as you want, and you can take it like every week. So maybe you can take several time at the same place until you get comfortable with the environment.
