I hate my neighbours but I think it's for no reason...but not sure

So I moved here 6 months ago and the first 4 months were fine, but since the weather has got better the neighbour on my attached side absolutely does my nut in.
I caught her kids jumping over my fence into my garden, I assume to retrieve a ball. Then the kids peer into my garden for no reason.
She has music on in her house all day it seems, so if the door is open you can hear it, then when she's outside she takes the music out with her.
The thing that really seems to irritate me is that she's always on the phone in the garden, whining about something and I don't want to be rude but the way she speaks just sounds so aggressive and annoying.
I used to live between two drug dealers, but for some reason this woman just gets on my nerves, way more than that.
I can't seem to shake this feeling that I just don't like her even though she isn't necessarily doing anything particularly bad. I'm not sure what to do as I think it's a me problem.

The kids entering my garden would have me exceedingly annoyed. If it was for a ball tell than that mim needs to come round and ask for it. Make it her problem. Meanwhile those plants need watering with a hose and pops if they hop over the fence …… If they are peering over, maybe trellis and some climbing plants or a higher fence panel may work. They will get bored after awhile, (unless you are doing something particularly unique!)

As for the owner - yes it probably is partly you and party her, because noise affects people differently and it might just be that her pitch/tone is the equivalent of chalk on a chalkboard or a dentist drill for someone else. I would try either listening to your own music or headphones and see if overtime your brain naturally tunes her out.

living close to other people needs a bit of give and take on both sides.

An ex neighbour of mine used to let her kids climb into our garden to retrieve balls too but when I asked her not to let them, she flat out denied they did it! Except I had it all on cctv.
