Feeling Alone Despite Having Support

(This post my be long, I apologize) Do you ever feel like you have no one to talk to, even when you have an amazing bunch of people supporting you? Like, I know I have plenty of people to talk to about my depression, and they are great at listening, but they just don't *get it*. I feel so alone even though I'm not, I just want to be able to tell someone about my feelings and them be able to actually understand and not just say something like "everyone feels that way", especially when I talk about my experiences in the mental hospital. Normal people think it's like a regular hospital stay but it is absolute hell.
