Hope I have done it correctly now.

SUBJECTIVE: This established patient is a 65-year-old white male seen for major depressive disorder with anxiety features. He has been prescribed Prozac 30 mg p.o. daily and BuSpar 20 mg p.o. b.i.d. The patient has recently found out that he has diabetes mellitus type 2, for which he has been started on metformin. He also continues to struggle with his Crohn disease. He has been feeling somewhat upset about his diagnosis, as he already feels somewhat frustrated with his problems due to Crohn disease.

I'd put a comma after "male" and check the spelling ~~> isn't it Crohn's disease?

It actually depends on account instructions on dropping the 's. Both are correct.

It seems like you are providing a patient's case history. Is there a specific question or concern you have regarding this patient's condition? I can provide information and explanations based on the details you have given.
