What is wrong with me?

a lot of the times, I feel extremely happy and hyper at school, and as soon as I get home I am depressed, or angry, for no apparent reason.
This happens all the time.
What is wrong with me?

ohh ohh ohh I've had that!!!
for me its my ADD
it works you up when your with people and things are good
then you have an emotional crash or rutt if you will when things are just blah or boring.
sucks..

Because you are a teenager with uncontrollable hormones. Think positive!

How old are you? You could be going through puberty and your hormones are just going crazy and the mood swings are normal or you could be bi-polar. Speak to a doctor sweetie.

Notes:
What Is Bipolar Disorder?

Bipolar disorder is a mental illness
People with bipolar disorder experience episodes of depression (lows) and
mania (highs)
Both men and women can get bipolar disorder

I'm like that. when I'm at home just leaving to go to school, I feel really down and upset because well, its school!! & then when I'm there, having a laugh with all my friends, I realise it isn't bad at all. then your back at home again, bored, friendless, and just.. pissed off because parents are parents... oh well

-Bad Vibes at home
-Bipolar
-Mood Swings

Idunno, thoughs are my guesses.

You dont meet criteria for bipolar, the mania isnt dependent on being at school for 8 hours... maybe you're bored and lonely when you get home, maybe it's something else... I dont think anyone on here can give you a diagnosis...
