Someone once asked...
Someone answered with kindness...
It's completely okay to do so. What you have done, has already been done, you can't change anything about it. So, there is no point in regretting or so. But remember, you also need to learn to enjoy by yourself. I know it seems hard, it takes courage, but once you do so, you won't stop anywhere. If you are to not do something because your friends aren't coming, you're never going to enjoy life to the fullest. However, if it's something like, a group of people (who obviously don't care about you) inviting you to do something, it's perfectly fine to turn them down. You don't have to waste your time over them.
