Playing sh*tty will ruin a neck quick 😆
No, it'll add a few more lbs of pressure. Check on the back of your string packaging, it tells you (around 100 lbs). You can compare it to other strings to give you an idea. May have to adjust your truss rod to accomendate... but you should be checking/adjusting this as routine maintance anyways.
Didn't catch what type of guitar/neck it was... could be a badly spaced nut, or misaligned neck/pocket.
