Living alone versus living with a roommate

When people go to (a) university, they will have an opportunity to stay at a dormitory.(dorm)
Most students live in a dormitory with their roommates because of limited dormitory capacity. In this case, some people enjoy sharing their room with roommates. When people have a trouble solving problems, they can together debate some their problem and they are finally able to have(reach) a good conclusion. If people live together, they will not be lonely. The reason why they live in a dormitory is their home is located in far from the university. If they share the room, they have a chance to get along with friends and escape from loneliness. But(However) I prefer living alone . There are reasons why I think so.
First, I spend my time enjoying what I want to do. When I suffer from my major(?? When I suffer from studying for my major), I should relieve my stress. If I want to listen to the music to reduce my stress, I can do so alone. If I live in my roommate, I should consider a roommate. (If I live with a roommate, I would have to consider my roomates preference in music.)
Second, I adjust my schedule for me. If I am a night owl, I am able to study at night and turn on lights. If it is time to go to bed, I should turn off the lights to consider my roommate.
Third, people are able to protect their personal life. If people live together, they have a chance to talk about each other. It is possible for them to reveal their secret by chance.
Therefore, I like to live alone without roommates

Good Job.  Instead of starting a sentence with "but" maybe try using "however"
