That actually makes a lot of sense.
I've felt that way before. I knew the truth. I was lazy and wasn't doing anything to improve myself or do more than I was doing. I was at home, playing world of warcraft, drinking, listening to music, watching movies, laying in bed.
Then one day my wife went from saying everyhing was fine with life to I was the shittiest laziest thing on earth.
I heard her.
I got a job, cleaned the house, tried to help and push myself despite the escalated drinking which she helped by buying me wine... but in the end, she left me anyway because she's just reached a point where no one and nothing can satisify her anymore.
But I hear you. I've been where you are before. i felt depressed about myself "just taking up space". Nobody is a waste of space that feels that way about themselves. Anyone who has thoughts and feelings and reflects upon themselves is more than likely a deep person who just needs to be heard and understood by someone.
