This is a dangerous topic. There are many who believe mental health is solely for professionals such as licensed counselors, psychologists, and psychiatrists to determine. What is dangerous is that they have legal backing that can make any contrary opinion liable. In those professions there is no acknowledgment of God, a change in life by the new birth, or even demonic influences.
Also, for those such as your self, who believe they have mental illness while being a Christian, comments will be negatively received and denied, so there is little use discussing it. My wife, for example, has known the Lord for 40 years and believes she has ADD. I have tried telling her otherwise, but have stopped commenting because she firmly believes she has a disorder.
What I will say is this. When you have the new birth your spirit is recreated and joined to the Lord, but our soul and bodies remain the same. We are exhorted to not be conformed to this world but to be transformed by the renewing of our minds. That process of mind renewal is up to us. We draw our own boundaries of how much of the Gospel we will believe.
