>>93140945Gwen seems to be in a depression spiral. Graduating high school is either one of the triggers, or one of the results of that spiral. When we actually see this part of the story, she's given up on life because she has zero faith in herself.
I'm thinking she was doing bad, didn't get the help she needed, and things just snowballed as they went on. She clearly doesn't have the support she needs to succeed - her mom is a bit of a pushover, and her dad just acts stern and probably makes her feel worse about not succeeding at things.
Honestly, I'm reading Gwen's story, and all she really needs is support and guidance. Batroc was able to mentor her and teach her how to fight, while her brother was able to inspire her to get her life back on track instead of throwing it away.
