Ha, writing! My first love.
I used to write a lot ; I would spend hours typing or handwriting without interruption; it was my favourite way of expressing myself. I was reading a lot too. But for some reasons, I kind of abandoned this discipline... but sometimes I feel the urge to go back to it. As if it was a calling. But I don't read that much anymore, and so I don't have substance anymore. But, like you, I want to practice again, more and more...
I've never considered taking lessons... but that's a great idea!
I hope you will find the passion, the patience, and the pleasure. :)
