From the advice of somebody in r/writing , the hope of one day getting published, and not offending everyone in a similar situation to my character; I’d like to get a better understanding of my characters situation. Hopefully people here can help and if not I’m sorry for coming into this sub. 

When she was young, my character was involved in a car accident. As a result of the injuries she sustained she doesn’t have any memory preceding the accident. The only memory she had is flashes of the accident (that I’m portraying as PTSD) that occur whenever she gets into a car. As a result she choses to walk everywhere in life. 

With the PTSD comes a severe anxiety attack that impairs her life for a significant amount of time. I’m saying for an entire day until she wakes up next morning. She doesn’t take medication often but when the panic attack is taking place it doesn’t help much, if at all. 

For the symptoms I’ve found what google says, but I want something that’s more than just what google says. I want to make the description as accurate as possible, but keeping in mind other factors that I’ll get to later. 

In the past her anxiety was much easier to trigger, and came about whenever she saw a car. After an unspecified amount of therapy, she was able to overcome it, to the point where she only starts to sweat and hear her heart pounding when she goes into cars or gets close to ones that are in motion. 

I would like to be as accurate as possible to the symptoms and feelings of a panic attack, but I also want them to be different in several ways. I have no idea what those ways are now. 

The differences I want are not, at least in my eyes, unreasonable. The world I’ve set the characters in is slightly more technologically advanced than we are. For example, cloning and genetic manipulation are possible. My character is in such a case as in she is a clone, and genetically modified. 

That’s why I’d like the symptoms to be similar, but different to the extent where it could be considered foreshadowing. Probably in how she handles the panic attacks or the symptoms that show. 

With all that background information I get to my questions. Is the way I’ve currently decided to depict my character accurate? If it’s not, what would you say is? What does it feel like to be under an anxiety/PTSD attack? Should I depict the anxiety with differences to foreshadow? If yes or no, please why. And what ways/methods do people use to cope with anxiety?
