Is it bad to get contact lenses for a small eye prescription?

I just got my first eye prescription and I think it is about -0.75 for distance. I want to get contacts but my eye doctor said having contacts can make my eyes worse faster because I won't be able to take them out when I do close work. I also heard if you wear contacts you're eyes become more dependent and that I will need a pair of glasses for when I can't wear contacts. Is it true wearing contacts will make my eyes worse faster? Would it be ok to get contacts with my prescription? I really want them! I'm 17 thanks!
Added (1). Oh and will my eyes get worse in the next couple years? How can I slow it down if they will?
