Mild Sleep Apnea & Severe Insomnia Ruining Life

I have had insomnia for 2 years. I can't function. I've quit my job, can't drive, lost my memory, cognitive abilities, fitness, it's ruining my life. I went for a sleep study and feel like I'm being gaslit. My biggest challenge is sleep onset. It usually takes anywhere from 2/4 hours to fall asleep. During said sleep study, I went toilet 4 times, including twice within the first 30 minutes. My partner said it was one of the worst night sleeps he's had due to how active I was. I could barely function the next day, I couldn't even drive to drop the machine back because of the genuine lack of sleep. I had vivid lucid dreams, and 7 total awakenings documented in my journey. However, these are my sleep study results - I am being told nothing is wrong other than mild apnea which they're not treating. I am not overweight, I'm sober, and medication no longer works (including zopiclone). I am desperate. What do I do? I did not sleep this night, my partner has confirmed this.

Sleep Quality Summary: Patient perceived sleep quality was poor same as usual night's sleep. Sleep architecture was average and consisted of 5 blocks of NREM sleep, with SWS totalling 10.3% and REM totalling 26.9% over 5 periods. Total sleep time was 458.5 minutes. Sleep was observed in supine and left positions. Sleep latency was 7.5min with sleep efficiency of 91.0%. Total arousal index was 12.7/hr. Respiratory Events: The dominant event type per hour were hypopnoeas and occurred most frequently in supine REM. Total AHI = 6.0/hr (Total RDI = 6.0/hr including Total RERA = 0.0/hr). Apnoeas / Hypopnoeas tended to occur in association with cortical arousal and/or oxygen desaturation, Spo2 desaturation between 2-3%. Average oxygen desaturation in supine sleep was 96% and non-supine was 96%. The lowest oxygen desaturation in sleep was 91%. Oxygen Desaturation Index (ODI 3%) was 0.5/hr. Sleep time with oxygen desaturations less than 88% was 0:00:0.0.
