How Can ADD Be Treated?

Hello, I am currently a part-time, semi-retired chemistry teacher. I was diagnosed with ADD several years ago by my family doctor. He told me I had a pretty severe case of ADD with extreme instances of being late for work and pretty much everything, lack of focus, procrastination, depression, and several other symptoms! I had somewhat coped with these things for years, but was at the point that it was severely affecting my job and home life. As I said, my family dr. tested and then prescribed Adderall-slow dissolving-long lasting? Good for 12 hours. My life became so much better!! ALL my symptoms were so much better!! Then 2 years ago my family dr. retired. I went to 3 different doctors before finding one I trust, but just like all the other drs. I have spoken with, in the state of Kentucky, many say that I need to be tested by a psychiatrist to obtain a prescription for Adderall. I am in dire need of medication for my adult ADD however, the psychiatrists that I have contacted in my area don t take my insurance! I really need medication for my ADD because it is greatly interfering with work but also much more in my personal life than it did a few years ago! I just can t cope, I can t focus, I procrastinate with everything! Could you please help??
