Am I perpetually stuck with depression due to my Ataxic Cerebral Palsy and chronic pains?

I'm asking this coming from someone who's tried different meds for my physical problems and even for my depression, I'm at the point where I'm a stoner now because medical marijuana is the only thing that won't give me adverse side effects.

I know depression is common with those who are disabled both physically and mentally, as a matter of fact this study from the National Institutes of Health says depression and anxiety are at a high risk for people with Cerebral Palsy.

As a note, I do have some family genetics that have given me other mental issues (I will not say what due to my past and privacy) that I'd suffer with even without Cerebral Palsy.
