Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
It would not be wise to wait for poblems to occur. Long standing depression
can damage the brain as well. Medicines are protective in this context. Ones you are diagnosed bipolar mood disorder
and still have persistent depression then you certainly should take medicine.
You can always try cognitive behavioral therapy
along with the meds. These are weekly session focussing on the thought process.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
