Sorry to hear about your job loss.
I think a deep breath is a great way to start (I just re-read the part about respiratory therapy
- no pun intended). This change can be positive. If you do decide to stay home with your child during the summer I'm sure you will enjoy it.
Some courses can be taken online too, whether you decide to continue to stay home, or work full or part time.
Take your time to think about options - sometimes what seems like a bad occurence in our lives may be just life's way of shoving us in another direction, with better things in store. I bet there is a silver lining here for you!
