Flow limitation evaluation is difficult to quantify but if you check the last 2 or 3 days worth of threads you will see some discussion.
Your flow limitation graph isn't particularly exciting though. I have seen much worse.
Anything that causes fragmented sleep is going to affect how you feel the next day because it messes with the quality of sleep and the needed sleep stage progression. So the mask issues, while not uncommon, are likely playing a part in how you feel.
Also look closely at the side effects that are possible from the medications you take.
Ativan...

This one in particular....Drowsiness
Lexapro

SSRIs are known culprits for not feeling so great during the day.
Not only do they cause drowsiness they can cause insomnia..trouble getting to sleep or staying asleep.
So you are taking 2 meds that have the potential to affect how you feel during the day and very likely are impacting things so some extent..how much we don't know.
Work on the mask problems for sure and talk with your doctor about your meds and their potential impact on your daytime symptoms whatever they may be. Perhaps a change in dosage or time of dose might lessen any impact they might be having.
I may have to RISE but I refuse to SHINE.
