Not liking the start of this 40s thing

So when I turned 30 I've dubbed it the year my body began to disfunction. Inner ear imbalance leading to temporary vertigo. The abdominal area as a whole picking up 2 new acroynms of life changing chronic conditions. I don't remember anymore what a normal fully healthy body feels like; I do know what normal for me feels like with every great once in awhile a slow awareness/realization of "oh, hey, is this what a normal body feels like" it's a wonderful moment that I try to savor for as long as possible. I try not to stress out when my conditions "flare." I thank God every day that my conditions are both mild to moderate and not disabling, I pray for healing in whatever form.

So when I turned 40 I was scared that something new would come or my conditions would suddenly change. So far "new" is my mouth. I have to get a gum graft and an information seeking biopsy done (no worries of cancer). I have some more major work coming in the Fall. And 1 of my conditions I've had for a very long time might have been misdiagnosed. But I won't know until the end of September - I have a inpatient procedure the 2nd week of September so I'll take prayers for all going well; and get results at the end of the month. If I have been misdiagnosed (which I'm not entirely convinced of) then I can get off a medication which isn't good to be on long-term and it's been long-term a few years ago. It's incredibly expensive, causes dizziness, and fatigue. Hence a good portion of my fatigue is medication based.

Part of me is afraid it will be something worse, part of me hopes it's something else that a differnet medicine would work better for me, part of me just wants well enough to be well enough.

I don't want my body to fall apart every decade. I keep reminding myself that my life is not my body, that whatever comes my way I can cope with with God's help and the love of my family and friends.
