I hope you feel better soon, WanToNeedTo
It's been said already, and I'm another person who thinks seeing your doctor is a solid plan. Only a doctor can tell you what's going on with these health issues.
I had a very bad flu once during my heavy drinking days. It was so bad, I had to stop drinking for almost a day... this shows how bad my drinking really was. In retro-spect, I know it wouldn't have been so bad for me if I wasn't in the depths of a nasty, daily, heavy, drinking habit. As StayinAlive already said: be careful with the cold medications. They can really chew your liver up...and cause anxiety. It's not a good idea to use some cold medicines when you are still drinking.
Feel better soon, k? Perhaps this is a sign that the drinking needs to stop. Your doctor can help you stop. I encourage you to be honest with a medical professional, and seek a medical detox.
