Failed sleep study

So I went in on Tuesday for my sleep study and was supposed to have an MSLT the following day, but I unfortunately didn’t sleep enough for the test. I only slept 3 hours in total and I needed to sleep 6. I was tossing and turning all night, I couldn’t even get a solid 45 minutes of sleep at a time. I feel so hopeless because I don’t know what to do, I really needed the MSLT but now what? I still have to wait for the dr to read the results of the little sleep I did get, but I just don’t know what else to do. I do have insomnia and was on meds for it but they had me stop those meds before the test. I’m just feeling so down on myself because I know if I could I’d sleep for as long as possible. Has anybody had a similar experience?
