More often than not, Sunday turns into my “sleep” day. In general, I have experienced hypersomnia (over sleeping) with my BPD and depression more than insomnia.
Hypersomnia is also a symptom of atypical depression. Links about atypical depression can be found in the resources section.
I sleep a total of 15 hours, on average, between Saturday and Sunday. During the week days, I sleep about 9-10 hours, plus a 2 hour nap in the afternoon prior to dinner.
For me, sleep is an escape where my mind is liberated from the incessant and fierce BPD commentary that seemingly never goes away. Sleep offers me a time-out from life and allows me an excuse to get away from people when I am tired of socializing.
I realize sleeping this much is probably not a good idea, but for right now, it seems to be a coping mechanism. It prevents me from getting into trouble, or from being impulsive and self destructive.
