"i'm always telling her about this stuff, but all she says is to not care and it's nothing. That doesn't help me at all. I really wanna solve this problems instead of ignoring them. She doesn't understand. I do know she cares though."
reading your response, I get the impression that the stuff and the problems you're talking about are external issues.. Such as some of the other students around you at school..? That are causing you to feel all these discouraging emotions?.. High-school, possibly?
..If that's the case, i'm not that much older than you.. So I can honestly tell you (because it's still so fresh in my memory) that for half of those 4 years, it was absolutely torture.. Everyone was out to trash me, everyone had large groups of friends but me, everyone was so happy to be in high school but me.. In every aspect, it seemed that everyone had it better than me..
Is this how you feel sometimes?.. Yes? .. Well, you wanna' know something?...You're not the only one! Yes, surprisingly enough, even those kids that seem like they got it all together go through some of these similar feelings, like you.. Like me.. Like everyone else. So don't feel like you're alone.. Because you're not.
I doubt there's one fool-proof way of dealing with this, since everyones situation is different.. But for me, I think the turning point was when I realized 'to not care' because 'it's nothing'... Sound familiar?? Yup.. You're mom could actually be telling you some very wise words.. Don't let the negative things around you get to you..You have to be strong, because, sadly, there are always going to be negative things around you in life..Whether it's just a mean look from a stranger to a disabling accident (**knock on wood!)..
And although it may seem unfair that other people don't have to go through the exact same thing as you, try not to constantly compare yourself to the people around you, because everyone is different in their own way..It'll eventually lead to a unique and stronger you in the future.
You'll see.. ;)
