Erika - I am so sorry that you had such a difficult time.
As others have said, I think we all have gone through this to varying degrees. (Great post Pengi!)
My husband was supportive but also challenged me by "pushing" me to be more independent here and not lean on him too much. Little things - like making me go place the food order when we were at the pub, or having me pay the cashier at the grocery store. He helped me not to crawl into a shell and hide behind him.
I never did learn to drive in the UK (his car had a sport gearbox and was a bear!) but thankfully we lived in an area where I could easily walk to any shops I needed. The bank, post office, doctor's surgery were also within walking distance. That really helped.
Again, as others have said, I think if you look at this as an adventure and accept the fact that there is a steep learning curve it will be easier to adapt.
