Are you not asking two questions here? Your subject is

Is it possible to overcome depression?

but within your post you are asking

How do I learn to love myself?

So, are you asking one, both?

I thought you were originally saying you were DISCOVERING yourself because you didn't know yourself. Is this not different from loving yourself? I'm confused.

I do know that I don't love myself and I don't know who I am either.

Is depression possible to overcome? I think sometimes it is but not always. Certainly not when it is attached to BP. Maybe you can learn to control it somewhat, but overcome it? NO.

If you're not BP, I don't think all depression is a chemical imbalance, some are but not all. You can be depressed over a loss of a loved one, via death, divorce, whatever. Is that a chemical imbalance? NIMHO. But there are other people who have a generalized depression. What depresses that person one day may be different than another day. That I believe is a chemical imbalance and not able to overcome, again control maybe, overcome, no.

Then again, I may not know anything about what I'm talking about. My brain is fried so who knows.
