I'm sorry for the pain you are going through with this loss. It might sound strange but my natural miscarriage had a faster grieving process than my D&C for a missed miscarriage. I think because through that pain you get to scream and cry and release a lot of the emotions.
As for the study, do you have any practical experience in this area? You might want to look into a course in massage that could get you opportunities with a local football club. Even if you start off volunteering, it might help you to work out exactly which path will suit you. I have a couple of friends who do this for metro and country VFL teams on training night and on Saturdays.
I'm not sure how your husband will feel about this though (as he sounds quite controlling) as you will be massaging the legs (upper legs ) of some pretty buff guys!
