How to break out of losing habit?

Recently i've just been losing way more then i win. I was sitting at a good 60% winrate in normals, i wanna start playing ranked but when i tried my losing habit went into ranked and i ended up losing 2 of my 10 games. really badly and had to get off cause i was rather mad. I really want to play ranked and get better but it feels like im getting the short end of the stick on teams. I know thats probably a bad way of thinking. I know its my fault to in some games. I usually dont have a problem winning lane unless im against a counter. Then i just play safe and if he gets annoying that im playing passive and makes a mistake i try and jump on them. I also ALWAYS ward when i push the wave. its gotten to the point that i do it out of habit and dont even realize im doing it. I always pay atention to jungle routes, especially since i started playing jungle lately, so i have a good idea of when the best time to gank me is. I'm also pretty good at cs'ing, i actually think its really cool when you can just CS with your abilities and damage perfectly. Its kind of like a ASMR effect for me. I could really use some tips and help with this. I know im probably messing up somewhere. Thank you.
