I don't know if you're interested, but since I am in this community, I am going to announce what has( what has happened to me from a long time ago) happened to me.

I have bipolar disorder.

Bipolar disorder is formerly called manic depression, is a mental health condition that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).
For example, someday (or even shorter; hours) you get very excited, but the next day you become very very depressed.
Just for no reason at all.
I can't get to sleep because it makes me very nervous.
My social relationship is getting fucked up by this
I laugh when I shouldn't be laughing
I cry when I shouldn't be crying
I am always nervous and confused about my emotions
I'm just having a very hard time living.
Emotions bouncing up and down, and you can't control it.
getting nervous is also very stressful because if you can't get rid of it,
you get stuck like me because it's very painful.
I cannot enjoy anything because of all the nervous thoughts.
Sometimes I get excited, but extremely.
Thats what I hate.

Conclusion

I could act very strangely.
Somehow people could hate me for my rollercoaster emotions,
but please understand me if you can.
