Extreme insomnia / no sleep

I had a miscarriage at 8 weeks on Saturday. Since then I have not been able to sleep but maybe 3 hours a day/night. Some nights I don't sleep at all and take a small nap during the day. I called into work Monday due to no sleep at all. I finally fell asleep around 5 a.m. and had to wake up at 8:30 to get ready for an appointment. Went to work Tuesday after not sleeping all night. I worked for 8 hours and then went to another appointment and took a small 3-hour nap. I slept an hour last night so I called in to work today and was able to get a couple more hours of sleep. I work early in the morning. I need to be going to bed by 8:00 p.m. but I just lay here for hours. I've been putting my phone far away from me and removing all distractions. After about 3 hours of laying here, I usually cave and grab my phone or a crochet hook. I don't know if it's emotions, hormones, or if I'm having some sort of manic episode. I don't feel sleepy during the day but I'm getting concerned about myself. I usually go to bed by 8:00 sometimes 6:00. I was considering asking my ob for sleeping meds. I don't know why but I feel nervous about taking them. Has anyone else experienced this? I feel like I'm going crazy! I have been getting irritated very easily and am just feeling so grumpy, I think it is a result of no sleep.
