Little update:
The thing is that I'm acting all picky and weird with people who are as perfect looking as I prefer :( And I'm ultra shy with people who are pretty or who I would like to start knowing little better. Usually i avoid even eye contact and lose control over my face/emotions.

The good thing though is that as I'm extremely tired of this situation, I want and I as well will take actions against being all like this.

If something good/negative will happen, I will update, as writing things like this down, seems to be rather motivating!

Thank you for your great advice!
