Hi Emily, welcome to the Depression Center. The answer to your question about funding treatment depends on what country you are in. As for what medication to take, the answer is the same no matter where you live... you need to see a doctor and get evaluated. Medications can be very helpful, but you need a professional to help you figure out if that is what you need or if there is an alternative. You are very wise for 18 years old... to be willing to seek out help is a very mature and courageous decision. There is hope. There is help.
