The problem is you will only know what it feels like if you experience it. However there are some great people out there such as your therapists, friends and family who will all try their best to understand and support you. You could have all of the information in the world on the topic, but still not fully understand it.
The best thing you can do to help a person understand is to try and explain it to them simply. You could use the flight or fight system as a short example. Of course, they may still find this weird...after all, panicking about getting into a car may seem strange to another person. The way my mum explained it to my teachers is likening it to a phobia. When I had severe problems with getting into school, my mum explained that it's like having a phobia of spiders. You're scared of them, but you don't know why.
The many people who support you and love you will try their best to understand and even if they don't, they will still continue to support you. As you've read in the last post, there are a few family members and friends that don't understand and have said that to me, but are still ever so kind. But there are people that won't understand and may be quite ignorant about it and that is their problem. Until they've experienced it themselves, they will never know. They may make sweeping statements or get angry - just ignore it and try to explain to them if they're willing. Not everybody is going to understand your situation, just like not every person understands every single maths problem.
Remember that you need support throughout your recovery, not people who don't care and this is where you have to be a little bit selfish. Keep going!
