Jackie,
you are not being 'negative' at ALL! I'm sorry you didn't sleep well.....doesn't make for a very good start to the weekend

And your battery pocket site is causing discomfort...... I know you are a 'small' woman, so you don't have much 'junk in the trunk' to cushion the battery, so you are more 'aware' of what's there......
I'm hoping you haven't recently lost more weight? You don't have weight to lose! But if you have lost weight, maybe this is why the lead wires seem to be protruding more?

Regarding the 'heating up' while charging....do you charge while lying down or sitting in a chair (meaning, is the charger between you and the mattress/couch cushion?)..... It could possibly be getting 'hot' due to being in a tight area.
Similar to when I'm on this laptop......if I have it on the bed, it get's hot because of not able to vent.......if I situate to where there is more airflow to the bottom, it stays cooler.

Another issue perhaps, are you charging while wearing 'breathable' clothing..?
Or do you have the charger up against your bare pocket site?
Do you have your unit 'on' while charging? Maybe try turning it off for part of the time while charging to give it a bit of a rest? I dunno.....just some thoughts off the top of my head.....

I hope your weekend looks up and you are feeling better!
