Is this diagnosis of bipolar disorder accurate?

Hello doctor,

I have been diagnosed with bipolar disorder two years back. Another doctor changed the diagnosis to light bipolar. The last one told me it is just depression and anxiety. I had mood stabilizers, antidepressants, and Modafinil tablets. Due to an overdose, I gained a lot of weight. So, I gave up on the medications cold turkey and started work outs and medications. I consulted a homeopathic doctor and started medications for depression and anxiety. I plan to go a nutritious diet for managing the depression, which lasts for three to four days when I am not stressed and longer when I am. Can a person be hypomanic for more than three weeks if he is bipolar-2? I used my willpower to accomplish more as I was moving to another country. I prayed more and started doing all the things systematically with planning. As my faith got increased, I started to become compassionate with people, and very confident about things. I was very optimistic about getting a new job and believed that God would give me everything I needed. I felt most of the favorable things happening in my life as god's actions. I felt very happy and present at the moment. I was not euphoric. I was not talking excessively, not irritable, or low on sleep. I slept for seven hours at night. I was not jumping from one idea to another or jumping from one activity to another but I was finishing tasks systematically in a calm way. Suddenly, I felt bored and depressed one day as I was not able to follow up on my exercise, diet, sleep, and prayers. Then, within two days all the systems in my life crashed. I felt depressed and anxious. But, I did not cry. I feel angry and lost in thoughts about my past. I just sit with my phone the whole day and eat a lot for many days. Then my efforts come back to get back into the system. I connect the feeling of happiness that was there a few days ago as euphoric and being productive as hypomanic. Is this bipolar 2 or just depression due to unsystematic living? If the praying and systematic part were hypomania, then if I maintain a good nutritious diet plan, do yoga and exercise twice a day and sleep for six to seven hours a day to fight the depression part, will the hypomania be controlled?
