It's not strange to feel like that. Sometimes it's difficult to share the things that matter the most with the people that matter the most. Just remember that there are always people there for you, however lonely you might feel, whether they're there with you or at the other end of an internet connection. And if you ever need to talk there will always be people to listen. At any rate, if it's a feeling Bon Jovi described it can't be abnormal can it? ("I may not be alone, you know that don't mean I'm not lonely")
