Please go spend a day in a classroom.
They send the brand new teachers to special ed. I spent one year working in the special needs classroom of a public school. It took so much out of me emotionally. Your heart goes out to these kids and thier families. So much so, that you have nothing left for your own kids and family at the end of the day.
Autistic kids thrive on a strict schedule and familiarity. If I were late or absent for a drs appointment, I had enormous guilt. I knew that was going to send a couple of the kids into a tailspin. I was pregnant and couldn't dare take time off to go to the dr!
It was rewarding and I got the warm and fuzzies. I also got hit, peed on, bitten, milk poured all over me, and very very little pay.
My suggestion for you is communication disorders. It makes more money than I can possibly comprehend. My sil has a masters in CD and bachelors in SW. She makes something like $45 an hour. TIme and a half overtime. Excellent benefits. It's seriously in demand, so she will never be unemployed.
She started out working with kids and now she goes to nursing homes. She goes in, has her one on one session and therapy with the patient, writes up her n otes and recomendations and then takes the next patient. She gets the warm fuzzies of helping, along with a fat paycheck, and rarely gets peed on or bitten!
