If you are paranoid, alienated, and not feeling love, then I would question whether you are happy? Wanting to be rid of things that weigh us down or make us stumble are always good reasons for therapy. I think true "happiness" in life doesn't have weights or potholes to stumble on. Yes, it might have problems but so do math tests, you just work on them calmly and solve them; they're not a weight or pothole (unless you didn't study :-)
