Some of what you are experiencing might be a generalized anxiety due to your new awareness that things are not going so well as you age. It happens to all of us, but the awareness (just in a routine medical exam if we're lucky, and not due to some crisis) and the drug reactions can gang up on us and remove our feelings of security.

It has been widely reported that statins can lead to problems, not least of which is achy muscles. I don't feel I have any adverse reactions to statins, but I did have a reaction to metoprolol, the heart-easing drug for people with atrial arrhythmias and/or incipient hypertension, which I sort of had when diagnosed with atrial fibrillation. Over time, the metoprolol left me feeling a bit 'gassed', unable to have the same output in physical work. Eventually, as I needed more and more of it to keep my disordered heart from beating too quickly when I had the odd run of AF, it would bump my heart into severe bradycardia, where the heart slows below 50 BPM. In my case, it went all the way down to 30 BPM which is the point where the AV node was keeping me alive. When all else fails, the AV node is supposed to sustain you at about 30 BPM. At that rate, even your intestines shut down.

I counsel people to do all the reading they can about a condition they have and how it can be treated....ALL treatments. Find out what works for you, and be an advocate for yourself with your care providers. Let them know you're doing poorly and they should....SHOULD...offer you some remedial help or alternative treatments. Sometimes learning about treatments allays fears about what could go wrong, or gives you ideas about alternatives that you can explore.

If one form of sleep aid declines in efficacy over time, change to another. Try CBD oils, zopiclone, and any number of other options. Naturally, this would only be with consultation of a professional.
