You need to evaluate why you are playing in order to figure out what you want to do. Much like any sport, there are different levels of commitment and no one can decide that but you. The one bit of advice I can give that will help you, both here and possibly anywhere in life, is to look at your outlook for your task and change it.
All the people who play a game, be it physical or electronic, that enjoy their pastime have roughly the same outlook. This isn't to win, but to have fun, to improve and to see what they are made of. If your sole reason to play is to win, then all you will accomplish is a self-fulfilling prophecy of dread and soul-crushing nihilism. You need to fail in order to improve, as you only learn from defeat.
I know that sounds like some hippy drivel you see in some bad Hollywood stereotype, but it is sound advice that couches have been telling athletes for generations. There are millions of combinations of actions possible in a given match, and victory only teaches you one possible winning combination against one other combination played by your opponent. Failure not only shows you what didn't work, but allows you to study habits you have that are giving you options that will never work. Every champion has more failures in their belt that victories (now whether those losses are in ranked, recorded matches is another thing), which is an encouraging thought for the rest of us just trying to do our best.
Figure out if you are playing for fun, or want to play for fun, and then look into things that will make that a reality. Or don't and find a hobby that will. Life is too short for one person to fret over things that make them unhappy for too long.
