Trying to silence your anxiety might feel like “forcing” because it takes tons of effort. I think it’s hard to force yourself to feel happy love feelings, and it’s a good sign that you feel best when you’re not overthinking. It’s still uncertain whether or not you “really love him” or not because not every relationship works, but I think it’s definitely damaging to pay attention to all that online advice. If you read a lot of it, it often contradicts itself! There’s no way to know which of that advice is right so I think it tends not to be helpful.
