A Challenge For Me

Now I couldn't act how I acted at home at other places other than my house... Til today, I dun even noe how I turn from a normal person to a extreme-quiet person... I hate my stupid-closed -mouth so much... It makes me suffer so much... It makes ppl thought that I am not friendly and many kinds of stuff... Act how I act at home to other places other than my house is really a challenge for me.. Can I complete this challenge?

These Problems Stil Exist

1) Face still have a bit greenish

2) Don't even know how to participate in whatever event around

3) Still dunno how to express true feelings

4) Face expression aren't natural

5) Dun even noe how to start a conversation with others

6) Still remain quiet (like acting proud)(but not true)

7) Easily get super shy/super quiet

Change and now changing back...

In msn, I tried to talk to as much ppl as I can... I tried to make some jokes to make ppl laugh.. (eventhough I stink at joking) But I didn't get any good response from anyone but ppl like reject talking to me(hate talking to me)... Or maybe if I like last time in msn wait for ppl talk to me+ talk some random talking subjects and stop talking nonsence, better?Or is just that I am too sensitive? (lol)
*When I was standard 6, my friendship thing is going very smoothly.. I have many friends.. But until somewhere around form 1, I changed.. Changed to quiet... Now I wanted to change back to the way I was at standard 6.. *I wanted to change already like a few years(f1-f3) ler.. Till now only I see some improvements... When I sit in the crowd, I will like panic and wanted to go somewhere else to sit... But now, I can overcome it already(I will sit in the crowd) Is this good? (dunno agn)
