Rising Above Victim Mentality

Is it possible that I’m the only one that creates my own anxiety, depression, melancholy, restlessness (dysphoria)? What if my pain comes from an external force? I’m being harassed at work, at school, my spouse abuses me, these things are real and they cause my dysphoria. So what does it mean that I create my own dysphoria?
Everyone is subjected to mistreatment, abuse, difficult circumstances in life… but the dysphoria is a result of how I am dealing with these issues. If for instance I see myself as a victim of the above circumstances I don’t see a reason to go through the difficulty of changing because I’m not perpetrating it, I’m being victimized.
When a person feels like a victim he tends to want to change his environment including people and circumstances as opposed to taking responsibility for his own condition. He then forgets that he alone has the power within to change himself and how he wants to react to it.
For example, if someone is or was mistreated by someone else it depends only on him how to react to it now. If Jenny was mistreated by her mother throughout her childhood she can choose to see herself as a victim and develop an inner script that says I’m disadvantaged because of what happened to me, I don’t have the tools that help every normal child to develop. That’s why I’m dysfunctional now and I experience depression and stress due to my past.
Or…
If Jenny chooses to be a productive, thriving person she is capable of writing a completely different inner script which will allow her to discontinue her suffering because of her past. She will even be able to use her hurtful past experience as a very productive tool to push her toward happiness that comes with the feeling that she fully recognizes who she is. The hurt she experienced becomes instrumental in her growth, development, and productivity. Happiness is not a tangible thing that we reach or acquire, but rather a deep inner sense that “I’m on the right track” and when a person feels that they are on the right track they can reach a level of confidence that will elevate them to a life in which they experience “self-actualization.”
