Hi and welcome.
FMQ does not come overnight!!! It takes patience, and a LOT of practice.
Gloves with rubber tipped fingers help you grip the fabric to move it easier.
Use as flat a surface as possible - if your machine doesn't drop into a table, then purchase or make an extension so that you have at least 15" or so to the left of the machine.
Practice on small pieces - 9" or so - to get the feel of it, learn the moves, practice speed changes around curves - etc. Make dozens of practice sandwiches to get the "muscle memory" down for each FMQ pattern you try.
Relax when sewing - make sure your shoulders are relaxed and not hunched.
BREATH - I know it sounds dumb, but it's easy to hold your breath while FMQ'ing. Don't forget to breath.
Keep practicing!!!
