[English Rose]

How are you defining co dependency?

I would define codependency as a disordered and unhealthy relationship in which one person definitely has either vice or some toxic quality, which is enabled by another person - due to compassion, a need to feel needed, etc. The second person might recognize that the relationship is toxic, but he or she does not set good boundaries.

An example might be a narcissist and an empath.

I am so sorry you are going through this April.  

Finding a healthier workplace, where you can shine, would seem a prudent move especially as there seem to be several toxic players.
