I think it is ok to imagine someone being there for you often if they are a close friend... but it has been to my experience that constantly needing that help makes people distance themselves because the negativity might get to them after a while. That was to my experience... I pushed 1 or 2 friends away because I constantly needed their help and support, and they got tired of it. What I learned was that I couldn't rely on other people to be my crutch and "hold me up" emotionally, so to speak. I had to be able to hold myself up, and they would be there to keep me from falling over.
