Dry Lips, almost chapped-like with some pink blotching at corners of mouth?

I never get chapped lips. I have used medicated blistex for 10 years now, several times a day and have never had a problem like I do now. For the past week my lips have felt sunburned, dry and to the point where I am using all kinds of lip balms every 5 minutes!! I have tried medicate blistex (white cream) Aquaphor, vaseline, burts beeswax (my doctor told me to use that) nivea lip therapy and another blistex with a higher spf. NOTHING is helping. I am using Aquaphor more than anything else because I at least have some moisture for a short period of time with that one. But after I wash my face, brush my teeth or shower my lips immediately feel like they are going to shrivel up and are very dry. There is no bleeding or cracking. I did have some cracks in the corner of my mouth but those healed and now it's just chapped there. I am so frustrated and uncomfortable. I even wake up at night having to put more vaseline on. I even tried NEOSPORIN!!! I was taking L-lysine tablets- once a day for a few days but I stopped thinking maybe that caused it. I just got some allergy drops for my eyes because my eyes were hurting, grainy and dry and I have a pytgerium in one of them. My eyes feel much better but now my lips are wigging out. Anyone know what this could be? Allergy? It came all of the sudden and won't go away. My diet has been the same, no new foods. Except I was drinking Iced Tea every day for 3 days in a row....And I had a little tonight. I am just afraid it could be something more serious. I have no more visits to the doctor for the year- I used all mine up. I have a horrible insurance plan. :(
