Still Sick

I've been sick with the flu on and off now for over a month. I've had to miss a lot of work and am still struggling with a deep rattling cough. I've mentioned quite a few times that my immune system is delicate but, I'm feeling pretty down about just how sick I've been. I've fought this with everything I have and it still doesn't seem to be enough. My doctor told me I need to stop being so stressed out about it and just be sick. Not being stressed is difficult with life concerns looming and everything needing to be put off. Trying to have faith that my body will repair itself soon and I will be able to pick up things where I left off a month ago and start to move forward again...
