I don't know if it has a name

I don't know what phobia or whatsoever it is but I am afraid of leaving our house or being away with my family. I was okay with open spaces but not with so much people, I feel like the space is getting smaller and I can't breathe. I can feel that someone may take me away if I am not with my family. My family is my comfort zone and it bothers me a lot if I am not with them. I just felt these 2weeks ago, maybe because of the stress I have at school. I wish this could also stop.

@FMB2010 I Googled fear of floors collapsing and it seems other people do have the same or similar fears. I suppose any therapist who is experienced in treating phobias would be able to help.
