does anyone else think about this often

the age of the body.. that it's just so painful, it makes you feel older than you are? (I struggle with this a lot)

I'm not even 50, and my body makes me feel about 200

thinking about the fact that it's so hard to do things that at my age should be so easy is so depressing, I even sometimes feel a bit guilty about it (even though I've put on weight and don't really exercise), the chronic pain isn't my fault

does anyone else feel like this, and when you start thinking about it how do you feel?
