When my daughter started school in 2000, I used the time to clean my house from top to bottom with my music blasting.
After I got that done, I volunteered at the school, almost daily. I ended up being asked by the principal to substitute because I was volunteering so much and they needed degreed subs. I subbed for 15 years. I still volunteer.
I also did things for myself such as spa day every now and then, regular lunch dates with friends, got my hair done, lunch with hubby, exercise and I even took a couple of short trips by myself to recharge!
One thing I ALWAYS did was to get myself up and ready daily. I still do this. If I look nice (not talking about walking out of a fashion show dessed up) I feel better about myself. If I am dressed and ready for the day I am more motivated as well. When I talk dress for the day, I mean I get up, shower, do my hair and makeup. My routine is less than an hour in the mornings. I wear nice jeans or a cute dress. The ONLY time I wear any gym wear is when I am at the gym. I never wear it as my daily dress.
You will find yourself in time. Be patient. Use the time to discover new hobbies, read a book, exercise, meet with friends and volunteer. Best wishes to you.
