Aww dear I know how you feel. Overthinking doesn't let me sleep sometimes and then I get anxious about everything, about my life especially, sometimes I feel like I'm not living my life as I should and that I'm wasting my life here but helping you here makes me feel better. I know that overthinking increases your problems but it also makes you realise some things and it keeps you watchfull. If you think about overthinking like something not that bad it would be better, I guess you'll learn how to live with it, one day and it won't be a problem anymore it'll be your adventage I hope xx
