Cracked lips

So, my lips goy REALLY REALLY dry two weeks ago and thet "cracked" (if that makes sense) about a week ago. They seem to have some blood and the lip skin is broken. It really hurts and I can't even eat, as it feels painful, tingling and itchy. I'm using the La Roche Posay cicaplast, vaseline and beewax (fragrance free) lip balm several times a day, but my lips won't heal. It's been exactly a week. What else can I do? I'm desperate 😭
