Jeez man. That's waaaay too much to ask. First off:
Happiness is an innately transient feeling. It cannot be maintained. Asking for a perpetual state of happiness is far too much to ask. This is what drug addicts seek. One must know how to enjoy happiness as it comes, then 5o let it go gracefully, when it leaves. One must seek to be *content*. Not happy. Contentedness can be maintained. And to get this, one must work for it, through setting short, mid, and long term goals.
Second: Humans can only see through their own eyes. What's more, we are only aware of 10% of what makes us us, according to the Fruedian theory of sub/unconscious minds. If you cannot even fully understand yourself, how do you expect someone else to? Someome can accept you, but truly understanding you is out of the question. Mutual dvotion is also attainable; however, it's likely that it will always be more on one side than the other. Though, sure, that could possibly happen.
Lastly, make sure you're treating your body and mind right. Depression often sets in when we're not eating right or sleeping right or exercising rught or socializing right.
In addition, maybe most importantly, as the Buddhist 4 Noble Truths say, 2 of them, anyway:
1. Life is pain.
2. The source of pain is desire.
You must find a way to rid yourself of these unattainable desires. Make new desires that can be obtained. Otherwise, they will cause you nithing but suffering.
Accept the things you cannot change. And find the courage to change the things you can.
There. I'm done preaching at ya. In any case, I wish you hard work and peace; because luck is bullshit.
