What can I do?

For this past week, i have just been having really, really bad games. Normally i don't feed but lately its just really bad for myself. I am constantly getting ganked, or focused to a much higher degree than my teammates. It has me kinda sad. It is frustrating. Despite playing casuals, or ranked 3s, i just can't seem to do well. I have had a great week irl, but i am starting to get discouraged to even start up league anymore. I am constantly facing plat+ people, who are usually much better mechanically skilled than I am. I don't really know what I can do to get my "mojo" back. Normally I play well enough, often get fed. But now i am doing the feeding, and quite horribly because I am not playing with people near my own skill level. Any advice, aside from taking a break for a few days? Because im at this point to where i dont even want to pick the game back up for a long while if i do take a break. The game this past week has just been anti-fun lately. Before this past week, it was fine. Now, it's just a chore.
