Hello, first of all I'm sorry to hear about your mother, and wish her well. Unfortunately if your doctor was comfortable in telling you that the chest pain was stress related in the past ( a very common problem), it may again be stress related to your mother or other stressors you didn't mention. At your age, the likelihood of this being a heart related pain such as a heart attack are minimal, and seeing as how it was treated before with anti-anxiety medications I would recommend getting another prescription for whatever worked for you in the past.
This will hopefully help in the short term, but I'd also recommend pursuing an activity that will help you deal with your stressors, such as yoga/ meditation/ any kind of relaxation activity (even reading a good book), whatever works for you.
If however you begin to feel that anxiety is not the cause because the meds aren't working, or your symptoms worsen or change, it may be worth having a more extensive workup. Since strokes and high cholesterol are in your family, they will be something you should monitor yourself for in the future to prevent having problems if possible.
I hope this helps, please let me know if you have further questions. Best of luck...
