Anxiety towards speaking, but not to all. Help, please!?

So im not generally a shy or anxious person but I have found myself in a situation where Im unsure as to why I feel uncomfortable speaking. Im 17 year

So i'm not generally a shy or anxious person but I have found myself in a situation where I'm unsure as to why I feel uncomfortable speaking.
I'm 17 years old and I live in a 3 bedroom house with my parents. I also have 3 siblings, so I've slept downstairs on the sofa for years. Recently, my older sister moved out to university so her bedroom is available to me upstairs!
You might be thinking, this is great! I was thinking the same.
Whilst downstairs on the living room sofa I skyped with friends (that I know in person) because I wasn't really able to be heard by my family upstairs. Moving into this bedroom will make me able to be heard as I skype with my friends by my siblings and parents, and although the conversations I have with my friends are completely clean and normal, this makes me feel really uncomfortable.

I'd love the personal space of the bedroom, it's all I ever asked for, but is there a way to overcome this fear of being myself with my friends infront of my family?

TL:DR - New bedroom next to sisters one. Afraid to skype with friends because sister can hear me. Not a shy person so wondering why i'm so anxious towards the idea of my family hearing me talk to friends.
