I want to get my first communion and confirmation, but I'm 16...?

Se always been a Catholic, but my mom was diagnosed with MS(Multiple Sclerosis) when I was around the age to get my first communion. I really want to get my first communion because it would mean a lot to myself and I want to get married in a church when I am older. Is there any way I can get my first communion and confirmation without having to be in little kid classes? Can anyone tell me exactly how I can get this done? Anything would help!
