Hi there and Welcome to HealingWell!
From what you have described to us, it sounds like the mis-carriage was the trigger for the return of the depression. I think making an appointment to see your therapist and your doctor is a good idea. What you will have to bear in mind though is that once you start medications, they typically take 4-6 weeks to become fully effective. Its good that you have recognised that you need the extra help again and that you are taking steps to improve things.
It sounds like you got some really good advice from Darren and Shy.
Just keep posting, we will be here for you until you can get in to see somebody. I truly think that counseling and meds will help you.
What concerns me is that you became so depressed at such a young age. You might have to deal with that. But hopefully the help that you will be getting soon will take you through it.
As I said, Keep Posting here. We will help you as much as we can
You are in my thoughts and prayers.
