Strumming

I’ll admit to getting a tad frustrated, I’ve posted a song on here about the subject. I love fingerstyle and chord melody but….strumming….it’s like my fingers are raking over gravel. Add chord changes to the mix and timing the change whilst continuing to strum..well I miss the strings every time. Fingers collapse like a house of cards. In a nutshell there is no continuity. Throw into the mix the triple strum and at the moment not a chance. Does anyone have or had these same problem areas to developing their strumming technique. On the road to this most necessary ability have you also stumbled your way to perfecting this skill.
