I have a 3 1/2 year old with autism and it can be stressful, I understand. Not to mention a 2 year, a full time job, and a husband who works out of town 3/4 of the year. Know you are not alone! I was so tired for so long and was sick of it. Now that I am eating healthy and exercise I have more energy. As far as the stress, getting your me time like you do is so important. I take my 20 minute drive to work and home to reflect, and relax. I listen to my favorite classical music station and it helps me decompress. Don't forget to give yourself mental time too. Even if it is just 10 minutes in the morning drinking a cup of tea. My son's principal also has a special needs teenager and she said it is so important to give yourself that time, even if it is only a few minutes in the morning. Let me know if you want to talk sometimes just talking to someone helps with the stress. I figure my son is always going to be this way so I need to make sure I am at my best to deal with it and be there for him. You also may want to take a date night once in a while and have mom/daughter days so they don't feel neglected as well.
