I need sleep

This past week I have been waking up about 2:30 AM and finding it very hard to fall back to sleep. So, am I not going to get a good night sleep again for the next 3 years??? I thought I would have a little more time to store the sleep. I am hoping maybe it's just that it's year end time at work and I am stressed to get everything done--and it takes me so much longer to do everything right now. Keep your fingers crossed for me and hopefully after the next two weeks I will sleep again. Well except for the nightly 12:00 and 3:00 bathroom breaks.
