Going back to the fertility clinic/anxiety

I’ve been noticing some problems with my sleep lately. My husband and I are going back to a fertility clinic in two weeks and I’m not ready to do anything yet as far as procedures are concerned but I feel like that is what is affecting my sleep. I also have a very stressful career as a special education teacher and have felt overworked all year. Our daughter is about a year old and I want to have all of the appropriate measures taken so we can start treatments as soon as we want to (this summer).

Any suggestions for a busy, full-time working, mom to one and hopefully two in a few months.
