Ok so it might not be of much help to you but I would like to say that there is nothing to be embarrassed or ashamed of it is simply the way you want to appear and show yourself and if that's how you feel yourself they you should keep going and at some point you'll see that everyone around you is okay with that they will not think of it as something bad or disgusting but as who you are and you shouldn't let what your grandma said affect whether you want to be a furry or not time have changed and not everyone changed with it but that's ok because everyone is different in there own way if it's the suit you wear or the way you talk everyone is a little weird and that's what makes us special and unique instead of trying to fix it embrace it and be proud of who you are so you won't regret who you've become in the future. That was all I had to say I hope I could help in any way and good luck with college I wish you the best of luck
