Few poems put exhaustion into such plain words. The speaker is trying hard to be perfect and admits it isn't working. Eating makes them feel sick, and not eating does too, so there is no safe choice left. The apology, "i'm sorry for being this way," shows how much guilt sits on top of the pain, as if the speaker blames themselves for suffering.
The line about the person they love being "trapped in another body" is the most striking. Judging by the wording, it could point to a deep sense of not belonging in one's own body, though the poem doesn't spell it out. The ending is direct and heavy: the speaker doesn't want to continue, doesn't want to be here. The short lines, the lack of polish, and the shifts between capital and lowercase make it feel like a private note rather than a crafted piece. The mood is tired, hopeless, and raw.
If this reflects how you or someone you know feels, please talk to someone you trust or a local crisis line.
