Dave has brought up some good points with his post Kyle, and I agree with him that it may be in your future grey's best interest to wait a while before getting one. I know you have wanted one for a long time but what is a few more years as you are only going on 19 years of age.
When you are the only one in your house then that grey has to depend on you and you only for its care and attention. I do not believe you would be able to provide enough time and attention right now and I have to think about the grey's needs and not yours right now.
Face it, being single you will have as social life that will take you out of your house a lot and school obligations and with only you to provide for your grey I think he/she will suffer from too much time spent by itself and develop bad behaviors. I know you would not want that for your grey and if you wait until you know you can provide the time necessary for a healthy relationship then it will be for the best.
You are a young man with a whole life ahead of you, take a few years to enjoy some life, make friends, date and finish your schooling and then get a grey when you know you are ready for it for it is a lifetime committment.
