You imply that prayer is purposeful on account of the fact it makes one feel better?
That's a gross oversimplification of its purpose that I wouldn't regard as accurate, but sure?
But do we not live upon this earth with billions of fellow human beings? Are our friends and family not capable of supplying counsel and conversation?
Of course we do, and of course we can. Are other human beings always present and accessible? No. Are other human beings always the right source of guidance for the situation? Also, no. There's no reason to limit yourself to communicating with human beings other than personal preference. If it's your personal preference to so limit yourself, that's your choice, but I don't find it appropriate to condemn other people as "wasting their time" for making a different choice.
And would that counsel and conversation be more valuable on account of the fact we are speaking with a tangible human being rather than some mythical deity whose only reply is silence and who has already determined all that you can say, all you can ask, and has already determined the answer.
Ah, and now we get to the atheist rhetoric. I was wondering when that would ooze it's way out.
All I've got to say here is that your personal experiences are not some absolute microcosm of everything in the universe. Theists can - and do - have "tangible" two-way communication with their deities. If you haven't had this experience, well... I can't help you there.
I also find it a little sad that you only find communication meaningful or bearing purpose if you receive a response. Hunting for a job must be painfully difficult for you, then. The way the job market works nowadays, you won't get a response on your communications the overwhelming majority of the time. Therefore, sending out job applications is utterly pointless given the low response rates.
