I'm talkative and can talk anything. Trying to be friendly but sometimes, I feel like I'm having this problem also.

I start to afraid of what coming out from my mouth and how other thinks. Started to isolate myself out from the group. Maybe it's true no one likes me. I felt down.

Is that social anxiety? How to solve such problems??

It's totally normal & alright to be an introvert ... at least you're not experiencing depression ...
For a start, start talking to the group of people you are comfortable with & +1 which maybe you wouldn't talk to ...
Slowly increase the number or ask your fren along that you can click with whenever you meet with new people ...
Then go to group outings ... by the time you reach this stage you would more or less be opened up to most people already ...
Good luck in this aspect ! 

I'm not depressed but I was bothered to a point where I would watch u tube and books for motivational stuff so I can improve myself.
Turns out they're not useful.
But I realize that the longer I spend with someone,the more comfortable I become.
But to certain people,I cannot communicate at all despite the efforts I put in.
*shrugs*
I guess this is me.
Gotta accept the awkward me.

Well, just be yourself ... you can't please everyone ... you live for yourself not for others so don't be bothered on how everyone looks at you..
just be bothered about those that genuinely care about you that will suffice.

yea I have this problem of overthinking what people think of me.
But I will try to be inconsiderate and dont care what people think.

Hi guys,

I think I have a mild condition of social anxiety.

I dislike being around strangers and people I can't click with.

I feel exhausted easily from social events. It feels like work for me to communicate with people.

I'm quite selective in talking with people.Some people I feel ok while some I don't

I tend to be overly self- conscious . Afraid of what Im saying will hurt that person or might not be up to their expectation.

I would say I behave differently around diff people.

AM I normal?
