Over committed and over whelmed

I think I over commited to summer work, at least for the first month of summer break.
I agreed to work ESY  which stands for extended school year, also known as summer school. School districts pay for students to receive special education services over the summer if there is a chance that the child might regress during the long summer break.
I have not worked ESY in 21 years that I have been employed by my special education cooperative. ESY has usually had enough speech language pathologists sign up and besides, I usually do group play based assessments in the summer (faithful readers of my blog will know this :)). However, a few weeks ago, our cooperative put out an all call to the SLPs, asking if anyone would be willing to provide speech services for ESY. There was a huge need.
I can never turn down the opportunity to work. If God puts it in my path, I feel like I need to accept it (within reason, of course).
So here is how my summer is shaping up so far:
I finished my school year last Thursday, June 11th. I started ESY on Friday, June 12th which goes through July 10th. I have done some private speech sessions and I took a two day class on Google, Google drive, Google calendar, etc. on Tues and Wednesday of this week.
And  I am teaching a continuing education class next week, on Mon, Tues, Wed from 12:30 to 4pm. And I am doing 9 evals in early July. And doing two presentations, one for a school district and one for a grad school speech language seminar.
Lots of commitments and some of these things are a bit out of my comfort zone which makes me feel uncertain and sometimes inadequate. Not that I am, I just feel that way.
Giving it all to God. I will do the very best I can and I will keep a positive attitude. Well, for the most part, except when I am having a mini-meltdown like I did last night. It's not that I don't want to work. I just want to do a great job when I work. I feel so responsible to the students and families that I work with.
I have never been very good at transitions, but I will do my best. That's all I can do!
