Psychiatric SD

Hi so I don’t usually post and I don’t usually talk about these things. I have Severe Panic Disorder, slight PTSD (at Vegas shooting Country Strong), depression, and in the process of getting tested for narcolepsy. I have tried pills I moved back home and just started at my home state school (10 minutes away from my house). Yes this has all helped but I have officially plateaued. I have had panic attacks in stores, classes, home, and while driving. I am looking into a Psychiatric service dog but am worried about the social aspect of it. I have “the perfect family” (so we make it seem) and I’m worried about my parents if I go through with this. Also how do I even bring this up to my parents (they obviously have to help me pay for the dog and training lol broke college kid here)? Sorry this is so long but I would seriously appreciate some advice. 😅
