How can i (18M) overthink less with my girlfriend (17F)
No clue if anyone in here can truly help me with this, but how can i be less obsessive of my partner, because every relationship ive been in it causes me to overthink a ton, small things, big things, i can overthink them, half the time i dont have proper reasons, but my mind instantly jumps to the WORST case scenario. Sometimes it causes me to have anxiety, and that can lead me to have less of, to no appetite, which obviously affects my eating.
I'll overthink texting differences, the way she acts with her friends compared to me sometimes ill think shes more excited with them than me, her mood if she seems upset ill think its because of me a lot, sometimes i worry she talks bad about me behind my back, the amount of time it takes to text back, shit sometimes ill even overthink because of a video i got on my fyp, and sometimes it just makes me overthink to the point i start imagining her with somebody else. I know its not healthy, but i dont know what i can do to actually lessen, or stop, these sort of thoughts.
For context, i took a year long break from dating, and thought i'd have healed from being cheated on, controlled, and thought i'd be more mature, but its an issue i have and can NOT seem to shake. She also took a year long break from dating for other reasons.
Any help is accepted i just need some way or ways to lessen these thoughts as i know it affects me and her sometimes, and i cant stand being like this so much.
