Some advice ?

Ok so, I'm not one to be as stupid as to talk about life complaints.
We all have them.
But to be honest, sometimes we really can't hold things in. I mean situations could get out of hand ,far out of hand and you'd have no one to talk to, or ask for help. Or no guide to life as to how to live it or enjoy it . Or be strong or be curious and be yourself , a happy person in general in a happy atmosphere 
I'm pretty sure that all of us as children had dreams, loads and loads of them that it influenced us to be good people.
And that when we went through puberty, our self esteem can easily die. Especially for girls more.
And when you turn 16 especially things can trigger you
I get that one can be so mad at something that he`ll start to be mad at other things as well. But is there really a good reason for that? To be so depressed and moody about something so little and take it out of its reach, just cos your sensitive? If someone has upset you and you go and maybe talk about it on the internet, or to a friend, or even cut yourself because of someone or hated yourself or what you do ,  sure things can be difficult , intact too difficult if you're a teenager whos been in difficult times, or even a grown Person as well.
Even grown people want to talk about trouble more than anything
Those who admit that it's really not a talking matter or that's it's no one else's problem seem to be taking problems so easily Into their life. They smile so cheerfully and easily it makes you feel happy a well.
But how do we know they're not suffering ? We don't. 
No one knows if we`re "going through serious matters"  not that we want them to. Unless you're a sadist that just needs attention .

It's not easy to forget hard matters that trigger you , BUT is it worth it?
No really, is it?
Holding up all that anxiety, pressure, sadness all for what?
Holding up loads of bad things in you is dangerous, because it can change ...example:
"That stupid uncle took my money without asking, returned it two weeks later and claimed that it was urgent, he gave me £20 more as an apology. What does he think I am? A sellout? I fall out for money? He pities me doesn't he? I hate it ! I hate him so much! I'm never talking to him again...god....he probably stole....no then he was afraid I was steel him back so he gave it back...idiot!!" 

Don't think. Be positive and think wisely and only wisely up to your mental level. you can do it. You can always change . But only and only if you believe it and be open minded to things.
