I usually just get that feeling on the internet. I'll type up a wordy reply to a post or comment, and think, "Eh, no one gives a shit," and delete it. I'd say that the web is the worst place to feel like you're making a difference. The best way, is to just go do things, and as often as possible, do them for other people.
Your first problem seems to be you expect praise or acknowledgement from other people for what you do. You're not that important.
Ultimately, nothing anyone or anything that has ever been or ever will be matters since we're all living in a doomed existence and through the passage of time all things will fade into the long, dark, and cold void of starless night.
Or all of existence comes back together, crushing everything that ever was or will be into a singular point small enough to be nonexistent.
But rejoice, you're the heir to an unbroken line lasting a million million generations and one of the few small pieces of the universe capable of contemplating itself.
So stop whining.
But i would say that you must balance that with your own reality becuase you will never please yourself if you keep focusing on the whole. You will keep comparing yourself to everyone else and you can end up even worse. I speak from experience, i know and it made me bitter and cynical. You need to have your own reality to build up then when you are at the point where you reach your goals, then you can look at a larger scale.
"If I try 10,000 different ways and something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward".

Ask yourself one question. Why do it? A lot of people make builds because they like making them. I write a story on the blog because I like writing it and my wife likes me to read it. I've a few followers here on the site but it's not the most popular story, it never will be. If you like doing something, add a discussion which you feel is important, or even add a piece of art and not many respond to it, why should that matter to you if YOU feel it's importance.
Hello mate, Firstly calm down and look at your whole situation, something has triggered this outburst, if you can figure out what the catalyst was, and remove it, life will get better instantly for you. In the long term? set yourself some achievable goals and reach them, give yourself a little reward for doing so. Never turn your back on a problem my friend, it will breed and multiply ten fold, and before you know it, it will eat away at you until there's nothing left but the problem. Try to keep an open mind and a pair of open hands, that way you will learn give and take, master that and you will master life its self. Good luck.
Why choose? Why must i give one to have the other? Why must i sacrifice my happiness to be right? Can i not be right while being happy? I don't want Seek to be disillusioned to the world, we are cynical because we have seen the world for what it actually is. I try to stay happy and not give up. I will not allow myself to be disappointed yet, instead i take the charge to make it easier for others.
