weird feeling

the last couple of days I've been having this weird feeling that something is off. I don't know if it's something with my friends or me personally, but something feels off. my friend invited me to do something on his birthday with him on Tuesday and I said that I would love to go but I will just have to ask my mom. after my mom said I could go, I started to overthink a lot and get a weird feeling in my gut. like I want to tell him that I can go, but after if I'm being annoying by texting him a lot or he doesn't want me to go. just a feeling that is keeping me from texting him saying that I can go and I'm not sure why exactly. like what if I do text him and than he decides he doesn't want me to come because I seem annoying by texting him. my overthinking is just really stopping me from texting him and I honestly have no idea why.
