Can guilt and stress lead to panic attack and fainting?

Hello doctor,

I had a thermal shock and I felt like I am dying. They took me to the hospital and she was there and saw me and the whole situation. I was not able to move my body. She was shocked, she was not able to say a single word just watching them taking care of me. She spent all the night crying. She could not stop herself. I called her all the night and tried to calm her down and tell her that I am okay and everything is fine but she could not stop herself from crying and she told me that she feels guilty because she was not able to do a thing while we were in the hospital. Since that day till now every night before going to sleep she starts feeling scared and sometimes she starts crying and when I ask her why are you crying she says I feel scared and I cannot forget the day I saw you in hospital. I thought it is just a matter of days till she forgets the whole thing but yesterday they called me and told me that she has lost consciousness while working. I went to her and she told me she felt like choking and her heart beats rate were so high and she felt cold. The doctor told her that she is fine and she may be so stressed and would have had a panic attack and this could have lead to such behavior. I told her that we need to go to a psychologist but as expected she refused and she told me that she can handle but I need to be around all the time whenever she calls or looks for me. I thought of taking her out to change her mood, going to walk or the gym to release the stress but she keeps refusing and telling me that she wants to stay in her room and she does not want to be around people. She just wants me next to her. That is all. What scares me the most is that she might have physical issues, feeling tired, and panic attacks add to the random high heart beating rate. Please help me.
