Flustered during FLs

I get 5-6/7 correct on most SB passages, but I genuinely tweak out on full lengths. Last FL I paused it mid B/B and started hysterically laughing at this whole process. I have a 3.9+ gpa and this test makes me crash out.

I got a 500 last FL, but I know my content knowledge deserves more than this. Scheduled for 05/23, but genuinely dk if more study time would even do anything. I have extreme test anxiety and the timer makes it so much worse.

I feel like giving up, but I can’t cause I can’t see myself doing anything else. What do I do?
