So i (20m) just got my first girlfriend (19f) we talked for about 5 months and we just started dating last week. She’s amazing and its kind of those corny lil love stories because we saw eachother when we were both kids and didnt think much of it, forgot about her over the years and so. I first saw her again last year and both my heart and jaw dropped when i saw how beautiful she got over the years. Everything is literally going amazing and somehow i still manage to overthink every single thing and let my anxiety get to me and let it bring me down and I absolutely hate it :(. I would love for anyone to give me a lil advice on how to cope with it because i would hate for it to ruin what im just starting to build with this girl.
