My name is [name_f]Catherine[/name_f]. My current nickname is [name_f]Andie[/name_f] (from my middle name), but I adore the nickname [name_f]Kittie[/name_f] and I wanted to try it out when I go to college. My family says they prefer [name_f]Andie[/name_f] to [name_f]Kittie[/name_f] (and [name_f]Kitty[/name_f] to [name_f]Kittie[/name_f]). I’m torn between the names and I don’t want to end up choosing something that I’ll hate.
So, which do you think is best: [name_f]Andie[/name_f], [name_f]Kittie[/name_f], [name_f]Kitty[/name_f], or none of these? Are there better options?
Yes absolutely feel free to try out a new nickname when you go to college. That’s the perfect opportunity to try something new. The only “danger” is if you go with one name and then decide you don’t like it after everyone already knows you by it (this has happened to me!)… but it’s not really a big deal, just a little annoying and awkward to get everyone to switch to something else. Maybe you can try out [name_f]Kittie[/name_f] now with family/friends before going and see if you really do love it? I would focus on figuring out which name YOU truly like best, regardless of what your family or others like. If you adore [name_f]Kittie[/name_f] then definitely go with [name_f]Kittie[/name_f]!
I definitely agree (and know from experience) that college is the best time to try out a new nn. Personally I prefer [name_f]Kitty[/name_f], but it’s your choice, and I wouldn’t worry too much about spelling, since it would mostly be verbal. And with family, maybe you could still be [name_f]Andie[/name_f] to them and [name_f]Kittie[/name_f] at college (that’s how it is for me). [name_f]Hope[/name_f] that helped a little!
[name_f]Do[/name_f] what you want, honey. It’s your NN! I think both are cute, but I like [name_f]Kittie[/name_f] more. (small personal bias probably… my hubby calls me [name_f]Kitty[/name_f]). If you want to change, do it!! 
This! You don’t only have to have one NN! I think it is sweet when different people have different NNs for someone. It shows the special/unique relationship you have with each person.
Example… my Mum and [name_f]Nana[/name_f] call me [name_f]Karri[/name_f], my Dad calls me [name_u]Red[/name_u], my hubby calls me [name_f]Kitty[/name_f], my lil sis calls me Kaybee, my bestie calls me [name_u]Kay[/name_u]… I love that each person (s) have their own take on my name!
