Hi T and welcome!
I am sorry to hear of the rough cold/flu season your household has had...and the resulting health anxiety that is has triggered. Being sick, even with something as common as a cold can be a real challenge for someone with health anxiety.
Try to be patient with yourself and the process of getting well. Your doctor just prescribed the anti-inflammatory and the inhaler...so try to give them a chance to do their work...
...and in the meantime, practice self help skills for managing the run away worries and catastrophic thinking.
At the top of the main forum page here you'll find our Resources. They are filled with great coping exercises that will make a difference in how you feel if practiced daily. There are even links specifically for Health Anxiety that you will find beneficial, I am sure.
Health and wellness to you, body and mind...
...and post with us anytime for anxiety sharing and support!
