In the sacraments, when we convey them, we do not act ourselves, but rather Christ acts through us, the members of His Body. As St. Ambrose says, "the one who baptizes is not Damasus, Peter, Ambrose, or Gregory. We fulfill our task as servants, but the effectiveness of the sacrament depends on You. It is not in the power of man to transmit divine gifts, they are given by You, Lord."
How could someone who is completely outside of the Body of Christ be able to act in the person of Christ? How could a non-baptized person give that which they themself were not given?
Not that it's very important here. I doubt OP would find a non-Christian, most likely a Muslim, who would be happy to baptize him as a Christian, anyway.
Also, OP, if you sincerely seek Christ and His Church, you will not be automatically condemned. Catholics call it "baptism of desire". If you are on your way to joining the Church, but death cuts your path short, Christ Himself will come to get you and complete your path. Of course, you should still try all you can to be baptized validly, but the whole issue of "which organization is actually the Church today", and the doctrinal implications that come with it, should be resolved first. I am Orthodox, I would tell you that you wouldn't get a valid baptism from a Catholic because they are heretics and do not use the right form. A Catholic would tell you that you can be baptized validly by about anyone who doesn't belong to a fringe cult like the Jehova's Witnesses. And a Baptist would tell you that baptism is not sacramental and not necessary for salvation so it's not an important thing to seek after.
