Recently diagnosed with auto immune disease, Love LoL and have time to improve- Can anyone help me?

I am a very private person, my entire life i have been introverted and mostly kept my issues to myself, but i feel I have no choice but to make this post. This is honestly an act of desperation. My name is Justin Pulley, and I am 22 years old. I was diagnosed 4 weeks ago with a disease called Auto Immune Hepatitis, but have been suffering the symptoms for around 9 years now. I however had no idea that i had this disease. I was once a competitive Halo player, and i traveled the U.S. with my closest friends to compete in MLG tournaments. I achieved little as far as going pro, but had a fantastic time, and came close to beating a team called instinct in a best of 5 series on my birthday. My handle was "Jspgameboy". These years were the best of my life. VOD: (https://www.youtube.com/watch?v=O3fAMriKMfg) As time went on i grew bored of the game, and my friend Kyle introduced me to League of Legends, and we started playing mainly bot lane. I have been playing since thresh was released, and the highest elo i obtained so far has been platinum 2. I love the game, even though it is sometimes frustrating. I have a great passion for competitive gaming and the esports scene. I have spent almost my entire life in the esports scene. I crave to be on a stage again, and compete at a high level. It is one of the few times I have felt truly alive, but I am struggling to become better at LoL. I am currently in the situation of being unable to work for the next two months until i (hopefully) can begin my treatments. The hospital I am visiting is very busy, and my appointment delayed. If anyone would be willing to take me under their wing, i can promise to be attentive. I have nothing but time, but patience with myself is growing slim rightnow, as i am in a frustrating situation. I could really use someones help. Here is a short video summary if you dont feel like reading - And a TLDR; I am currently out of work due to a complicated health condition and am attempting to play League full time for the next two months until i can begin treatment, but am stuck in low plat and in need of help.
