Do I worry too much?

I've realised i worry lots about the gerbil babies, some days I can just sit and watch the gerbil cage incase something happens so I'll be there for them, I forget all about school, and almost came too late to my job, because I was watching the babies... ^^
I love those babies with all my heart, how will i ever be able to give them away? I know i have to be realistic, we can't have the appartment full of gerbils.... But I love them... I know i can't keep them and my boyfriend won't let me, so I'll just have to enjoy the time I've got with them. The breeder of the two gerbils we had from the beginning (Marvin and Zero), has promised to buy the babies from us when they are old enough and to take good care of them, so at least I know they'll have a good home.

I don't think I can have children of my own because I would just worry myself to death ^^
