is it possible to live alone and be happy at the same time?

Recently, my mother and I have got into serious talk about me living alone. I decided that i want to live alone after a couple of years or so when i finish college. My mom said that its "dangerous" to live alonea and told me a story (in her words it was real as she said) that an old lady nearly died because of a slip and fall from a wet floor and broke her leg and no one was there nearly the whole day until her neighbor stopped on by to check on her and knew what was going on. I can't be sure if that was real or a simple scare tactic just to force me to have like some friends to trust on but to me i WOULD want to have like a good friend i knew of but i dont want to create such drama in and around an apartment and then so on. I also want to live alone because i want to have some kind of relief, peace, and quiet that i needed after about a few years working with my parents and being called on upon them so much and starting arguments and small fights. Then afterwards, never to speak a single word to them for who knows how long...or maybe call them every year or so. So is it possible to live alone and be happy (not counting the job)?
