Safe Driving Exposure
Hi Em,
You're in the right place here :) I have the same sorts of experiences, only my fear is vomiting, not fainting. For starters, and the thing I am having most problem believing myself, is that you really don't have a reason to faint. From what you've said, doctors haven't diagnosed a medical condition which would cause you to faint. Other than that, you've fainted only when talking about blood or injury, which is extremely common for a blood-injury-injection phobia (it is an actual thing, I promise). I also am prone to fainting, especially when I see an injury. But the injury itself, nor the images that flash through your mind, don't cause fainting. Otherwise everyone who sees blood would faint and doctors wouldn't be able to do their job. I know for me, and most likely in your case too, it's the hyperventilation that causes fainting. There is a section in this program on relaxation, which includes box breathing and you might find this useful. Also, you've had all these panic attacks and not once fainted. If you need reassurance, there is a question about this in the Questions to the Expert link at the top of the page.
With the phobia, there are techniques called desentisation and gradual exposure. Desensitisation involves thinking about injuries and looking at pictures, you might start by looking at a picture of someone with a small cut and feeling the fear but not giving into it until your level of fear decreases. Then, gradually you work your way up to looking at a picture of a gory injury. After a while, your tolerance will increase as your fear decreases and, although you probably will still be afraid, you aren't as afraid as you have been in the past. Section 4 in this program talks about this too, but it's specifically for panic disorder and works on gradually exposing yourself to situations you fear experiencing a panic attack, such as driving.
Another thing you may find helpful is having a plan for if the situation you fear were to occur, if there is a chance it will. This might include making sure you have some water and some form of sugar when you start feeling light-headed. Or while you're driving, winding your windows down so you have fresh air might help. I can't really think of any more off the top of my head, but hopefully you understand what I mean. It's almost like having an escape plan in case of a fire.
I hope this is helpful.
Best of luck,
Kaitie.
