The traditions of the Church generally suggest that any baptized person can baptize in an emergency. An emergency here would be in danger of death (ie, from disease or war or wound, etc.), which would NOT be true in your case.
The best case for you may be to reach out to a priest in a nearby country and do a brief course of catechism (instruction) remotely, and then either visit him or have him visit you for the baptism. Most clerics would be willing to make a special effort to visit such a person, and consider it a joy rather than a burden.
A church building is not necessary for baptism (indeed, baptism is still sometimes done in rivers). If you find a priest willing to come to you, even five minutes with three cups of water in a bathtub would be perfectly valid.
