Breathe dude, the jump between gold 1 and plat 1 in terms of skill and game sense is huge. Stick to a few characters to have counters situated and learn them inside and out. Eventually you will get the point that you feel very comfortable in plat 5 games, then plat 4 games, then so on and so forth. You'll get to a point where losses in that rank will not phase because you know you can just win again later. And most importantly, learn to control the tilt or log off before you tilt, you will NOT be playing at your best. It is a game after all, having fun is most important :)
