Hi IT Guy

My advice for what it's worth is:

1 - only drive if you are safe to, consider others first
2 - get out there if you can as it will really help you to regain your confidence and indepence - i find the following helped me:
a) start with a small drive, at a quiet time on roads you know, to somewhere you know. tell someone you are doing it, someone that can come and get you should you feel you can go no further. or perhaps have them in a car behind you so you feel as secure as possible?
b) start then building it up, but taking note of how you cope - if a 20 minute drive is too much, then limit it to 15 until you can do better
c) avoid rush hour
d) avoid motorways - I am driving now but still get very freaked out and fatigued on motorways, to the point I feel i have to pull over onto the hard shoulder and stop - so now I don't do that anymore

3 - small steps in the right direction, and a give yourself a reward each time you've moved towards your goal
4 - realise there will be set backs, you may be perfectly ok driving one day, but another it may be too much

Good luck
