I just realized my gameplay in LoL is like a non-committed relationship

1 - I find someone else I haven't played in a while 2 - I play them, get obsessed in their mechanics 3 - I start to enjoy my first few games 4 - I suffer one or two tremendous losses as them 5 - I lose interest in the champion thinking they're not the 'perfect' champion for me

And the cycle continues...... .....which is why I have such a high MR score but hardly anyone in MR7..... .....which is also why I can't OTP even though I've been wanting to for ages.....

Anyone got any 'psychological' fixes for this? It's been 6 years and I still haven't begun to OTP anyone and if you're gonna say you don't need to I really want to but this 'mindset' always breaks me

EDIT: I can't cs well so I stick to support or jungle
