Don't beat yourself up. I actually am just shy of a Bachelor's in psychology and Interdisciplinary Social Sciences and I missed everything. Because I was right in the middle of it. Honestly, with H's family, I was waiting for signs of alcoholism and depression, but it didn't start that way. I too noticed them, they just didn't make sense individually. When you look back and put it all together...That is why they say hindsight is 20/20.
"Acceptance doesn't mean resignation. It means understanding that something is what it is and there's got to be a way through it."--Michael J. Fox
