Please let us know how you are doing.
My suggestions: Speak to your T and pdoc - they can possibly make arrangements to get you to the hospital.
What about a taxi, family or asking the hospital to send an ambulance?
I really wouldn't worry about there being any legal implications if you drove yourself, as long as you feel you can cope. Try not over-medicate and only drive if you have let the meds work out of your system for a while e.g. sleeping tabs.

The issue is before you right now. You cannot let financial issues stand between you and something even worse if you don't get to the hospital. The financial issues can be addressed later.

Thinking of you; please check in ASAP with us.
