I think this song is about his battle with depression, "indoor living" itself is when he cant face being with people, he feels safer when he is alone. "so don’t ask me out don’t make me try
cause i don’t wanna let you down" he cant face going out and being with people because having depression is stopping him from being able to be himself and live his life as he would normally and feels that he will let people down who are close to him. He stays indoors because he wants to protects himself from othwers, and protect others from being let down by him.
