Yes, everyone is different. Some medication can be necessary, but we should not rely totally on what the doctor says.
I was told how wonderful modern antidepressants are and how much less side effects they have. I had taken a 1950s model antidepressant about 10 years before. The modern one, an SSRI, made me feel so bad I longed for the bliss of my depression back. Then the doctor said, "Oh, but there is a better one with less side effects." This was an SNRI and was worse. It messed up my metabolism so that I went from slim to obese in 3 months without changing my diet. It took 4 years before I felt free from those side effects, including my obesity, and every doctor I saw in that time was surprised. "It shouldn't take so long to get over a side effect," was their mantra.
Then I was referred to a doctor who uses medicine creatively off label. He put me on to a medicine that works opposite to the standard antidepressants, and that worked wonders for me.
I have ADHD and stimulants do not work for me. I prefer being ADHD and coping with God's help rather than being a zombie, which is what I felt like on stimulants.
So medicine can help. As I have said before medication does not cure, they reduce the symptoms. Different conditions need different treatments. Also different severity needs different treatments.
