Life frustrations......

Sorry, but this post is one of those where I am just needing to vent. Bear with me and pray for me if you could. I know the details are vague, but I really don't want to delve into it all.
A month and a half back my daughter had some health issues. After a few trips to the ER and her doctor and another doctor, we think we have determined what is happening. The doctor has put her on some meds. My frustration is that she is still not feeling real great. She is nauseated alot, she still has some pain issues, though not enough to warrant the ER again (thankfully). But, as I sit on the outside, it is frustrating to know that I am doing all I can and it doesn't help. She can go from fine one minute to horribly sick the next and then back again just as quickly. Sometimes she just stays in sick mode. And, yes, we have days where you wouldn't know she had anything going on.
*Disclaimer.....I know there are parents out there that have much more on their plate....they have children with many more health problems than mine experience.....but, this is my reality, and right now I am overwhelmed.*
This in itself might be okay, but this is not the first issue dealt with. Last year about the same time, my son had some medical issues. Again, not sure what to do. Ended up in the ER with him only once, but home many random days, and late for work often. After many trips to the doctor, many tests, and finally a specialist the figured out what was going on, put him on temporary meds to help the issue and we have been going through life since. He is slowly getting off his meds, but is still occasionally having problems which the specialist isn't sure why. They tell me to get him off his meds and see how it goes. Of course, as a parent I want to know why there are still issues, but am hoping that once he is off his meds things will smooth out. No guarantees we won't run into this issue again though. Another sit, watch and wait scenario where I can do nothing to fix it.
I sometimes find myself in a mode where it must just be that they are honing their dramatic skills for the next Oscar, but can tell by their faces or actions that it usually isn't. but, I hit that mother mode where since I don't know what to do, you just need to get over it and get moving. I know that is not the most compassionate, but it is what it is.
So there you go. I know God has a plan and a purpose, but this is one of those times that I just can't see it through the fog of everyday moments. And, I am tired........
(This post was brought on by one of those rough days....woke up sick, then okay, then better, then BAM......)
Thanks for letting me vent....
