Should I quit ranked?

It seems to cause more harm than good for me. It just leaves me feeling bad when I do poorly and making me feel mad when my team mates do poorly. Ranked is the most stressful part of the game, you feel so stressed when you have to win 1 more game in a series too go up, or when you are at 0 lp and 1 more loss will demote you. I find it really frustrating because I go on a huge win streak get 100 lp and then in promos I either get potato team mates or become a potato myself and then lose my series and slowly go back down to 0 lp.
