Thank you all very much for your answers and advice :)
It helped a lot really, also thanks @Connie for posting that video.
I think I will go to sunday service the next sunday, because I promised my mum to visit her on this one.
And yeah beeing shy isn't always easy but I'm ok, as long as others take the first steps in talking to me.
If someone starts talking with me, I soon lose quite a bit of my shyness.
I mostly have problems starting a conversation.
I hope you all have a great day
