@Darla-Alphalfa oh i wouldn't worry about it, these things come along when you're least expecting them and if it's the right person you'll find a way to make it work. The fact that you're a thinker/overthinker tells me you're one of the good people. I'm always accused of thinking too much. I always shoot back that they don't think enough. I know it can be a burden but it's one worth having. In this instance it's saved you from falling prey to a player Darla, keep being you, it's a good thing indeed!
Meditation, especially Mindfulness meditation is a good start... it helps you get in control of yout thought. certainly helped me out a lot last year. Then, an honest and deep introspection might help you out a lot as well, think about things about you you've been neglecting or straight up repressing for a while now. this might have some side effects but it is good on the long term.
