I know this is one of those questions that really requires a professional's answer, but for those of you who are living with anxiety, what does it mean when a person is often worried about things going wrong or frequently thinking about unpleasant what-if possibilities? Or if they can't ever relax 100% and fully enjoy happier times because they think something bad will happen to ruin the happiness?

Would that be consistent with GAD or some other form of anxiety? If the person has experienced the loss of a family member, job loss, etc. and is having these worries in part due to that, would that also perhaps indicate a form of PTSD?
