Drained,
I too suffer from depression, so I know how you are feeling. Please take your therapist advise and write down how you are feeling. Take some deep breaths and try to relax. You are not a weak lady, but you are stronger than you think. Be thankful for the good things in your life, your girls, and all of your health. Take it one minute at a time if you have to, and be thankful you made it through that time.
I have your phone number and will call you later today. I will be working but will call any how.
Your family will be there for you if you pick up the phone and call them. Your family here is always for you too. So you are not totally alone, but I know you feel like you are. If you want to go look for another job, school starts soon again, and it will give you something to do. Take babysteps right now, don't worry about what might happen look at today as a present from your HP.
Turn to your HP since he is always with you and will always show you the best things for you to do.
Hugs and prayers coming to you
