Right now you are feeling victimized, aka "feeling sorry for yourself."
Feeling victimized by life/people means that you are relying upon other people to make things happen for you and they have disappointed you - which they will. It's time to take charge, and get things done without relying upon others.
I noticed that you classify "you" versus "them," and "good" versus "bad."
Treating people the way you know they would want to be treated is implying that you know what is going on inside of their heads. People can sense this, and resent it. You should instead simply, be yourself.
Thus observed, I see you as a controlling personality, and things are not proceeding according to your expectations: that is why you see good things are being followed by bad things - people do not like being controlled and will rebel against control, and they will create obstacles to prevent that control of them taking place.
I myself cannot say what a humble personality is, nor what good nor bad is, unless I have expectations - if I did, then I would be a controlling personality, since I would be placing judgments upon what is occurring around me, in order to assess whether my expectations upon others are being met or not.
Shift your perspective on achieving what you want for yourself, and away from expecting people to react favorably to your manipulations, and thereby delivering your happiness to you.
If nothing else, you will feel enobled by doing your best in meeting life's challenges, and
when your personal efforts do pay off, it's even better. But we can't always succeed, otherwise we would never continue to strive to developing ourselves into better people.
That is to say, you can find happiness all on your own. You will have to learn to be happy with yourself, and being happy alone with yourself. That is, proof self-esteem exists. When self-esteem exists, you will no longer feel the need to control. The need to control stems from fear. Fear cannot exist when you have self-esteem.
Self-esteem can be defined as self-confidence, and truly having faith in yourself.
