My Life as of Now, Feedback Needed

I am 19, parents kicked me out for no reason other than that i was out of high school. I support myself, pay for school and my life right now... well here it is... I hate where I am living. Not just dislike but hate. I feel unwanted. This isn't my place or my room, I have a space to put my stuff and sleep. I feel unwelcome in the house and I am only in the room. I dont eat dinner at the dinner table, I eat alone on my bed. I feel like an inconvenience when i use their kitchen or their appliances. I rarely go in their living room, only time i do is when im watching their kids. They eat my food, drink my drinks. I can't afford to feed myself as well as 5 others. They go in my room when i'm not home, walk there dirty muddy dogs through my room daily, they dont even clean up after their dogs. They leave the room door open to outside and my room is filled with bugs by the time I get home. My stuff has been gone through countless times. I feel like a burden and i have nowhere else to go so i am stuck here. And I can't talk to you cause it is so depressing how miserable i am. I dont have a home, I feel like i have nothing and im barely getting by. I dont know what to do or what you want me to do. I am trying to support myself and go to school, i cant even finish classes because i have to work. If i go to my classes then i cant work, and i cant support myself. If i work then i cant go to my classes and im stuck working mediocre jobs all my life because i have no other talents other than school, people can get by and do well without schooling, but i cant, i would be nowhere, any advice?
