Yes, this does sound like insomnia. I know how distressing insomnia can be.
There are different types of insomnia-the type you are experiencing is acute insomnia, also known as adjustment insomnia or transient insomnia. This type is typically temporary.
The treatment for your type of insomnia includes making sure you avoid caffeine, especially in the afternoon, avoid smoking, trying to exercise regularly, and trying to fall asleep for no more than 30 minutes. If you cannot sleep, get out of bed and do something. Then try again.
Here is some information for you regarding sleep hygiene:http://www.umm.edu/sleep/sleep_hyg.htm
Short term sleep aids can also be used--over the counters and prescription if necessary.
Melatonin is helpful for some people.
