I think it takes a strong mind to overcome that belief framework.

That's not to say it didn't have inherent worth for you while you went through whatever you did that made you feel that way, but finding flaw in your own arguments/belief systems is a pretty significant skill set to learn too.

Learn to be resilient against yourself. Learn to take risks against yourself. Learn to fight harder against yourself, than anyone will ever fight against you.

Maybe you can, maybe you do, but that loop that brings you back to suicidal feelings is neither strength nor weakness.
