Most of us have issues...
we really can't do anything about that.
--if that's your way of thinking, you'll definitely have a hard time being at peace with the people around you because you are going to have to deal with different attitudes on a daily basis.
Now if you have a good attitude, people will be drawn to you. But if you don't, you know the rest.
And so, maybe it's time to drop the "who cares?" question and start thinking "at least I care about myself, and I don't want to be clashing with anyone at any given time." It sounds selfish if that's how you take it. But it's a step. Initiative does start with an "I", you know. It's not impossible, it's just how you approach it. Your way of thinking really makes or breaks any attempt you make for anything!!!
But then you say, "you don't understand. You don't know what I'm going through." Yes, I am not in your shoes, I don't know how you feel and I don't know the things that you have to deal with. But realize that the things that you go through, all the bad things that bring you down, are catalysts. If you don't hate something enough, you won't leave it or stop doing it. You won't change because you're thinking to yourself "it's not ALL THAT BAD, right?" Or you'd say to your self, "Oh, I'll change eventually." "When so and so happens, I'll change." Well, it doesn't work that way, It's either you decide for yourself and start working on it. Like what my friend would say:
It has to get worse before it gets better.
These bad things that you can't bare, make you appreciate and cherish the good stuff. The Bible talks about a list of things that you don't want to experience and equated them with wonderful promises--they are called the Beatitudes.
