I've been thinking a lot lately

And I really don't think my boyfriend is the same person as he was. He has changed so much. he's become so reserved into himself and it's hard to get anything out of him. He is so depressed, and I am so worried about him. He refused to eat at all yesterday, and he's still refusing to eat today. I just left half of an apple turn over next to him in hopes he'll just eat it. He works from home, and right now he's just working on his bed. I have tried so hard to do everything I can to help him but he won't take any of it. His therapist is on vacation so he's missed two weeks of therapy and it's really showing, luckily he has an appointment with her on Monday.
He also had a consultation with a psychiatrist last Monday and he was told he could quite possibly have borderline personality disorder, but they would have to do more thorough testing to figure that out but for now theyre just giving him new meds to help fight his poor mental health. He also has an ADHD assessment on Tuesday. They're really testing him for everything. I can tell all of his doctors are very worried so I hope he gets the treatments he needs.
For us, I think me and him are done. We haven't broken up yet because I find it extremely hard to leave him when he is in the most need he has ever been in, but at the same time I feel like I'm holding him back from healing. I don't know man. Shits hard.
