I'll answer your question from a legal and from a mental health point of view. I can't type Chinese so if you need translation, Google might be able to help you.
From a mental point of view, you should have already been given a diagnosis. If not, most likely you were have a psychosis episode or could be more serious disorder like schizophrenia which would require you to seek attention from a psychiatrist or psychologist.
From a legal point of view, if you have already been given a diagnosis, then you can plead guilty and then ask for a record of not criminally responsible
HK Laws. Chap 212 刑事訴訟程序條例 Sec. 74 基於精神錯亂的理由而被裁定無罪
"凡任何人所被控告的罪行是任何作為或不作為，而在就該罪行審訊該人時，所提供的證據是該人精神錯亂以至按照法律他在作出該作為或有該不作為時無須為自己的行為負責，而如陪審團覺得於其席前受審的該人有作出被控告的作為或有被控告的不作為，但在作出該作為或有該不作為時是如前述般精神錯亂，則陪審團須作出被控人因精神錯亂而無罪的特別裁決。"
However, you must be careful in pleading yourself as mentally not stable as you might be committed to treatment by court under the Mental Health Ordinance (HK Law. Chap 136)
Chap 136 精神健康條例 Sec. 57 根據《刑事訴訟程序條例》被命令收納入精神病院內的人
即使《刑事訴訟程序條例》(第221章)第76條另有規定，任何人如因精神錯亂而被裁斷無罪，行政長官仍可命令以其他非該條例所指明的方式，將該人羈留扣押。
You can ask for legal aid, however, it will depend on several factors like if you pass the income assessment.
醫生可唔可以阻止, 推番供詞: If a medical doctor gives testimony, that will weight more than what social worker said, but it will not be over-ruled.
Chinese Medicine's diagnosis on mental health is unlikely to be admissible in court. I suggest you talk to a psychiatrist or psychologist for a court report.
Good Luck.

Penalty can range from fine and/or community service order to nothing (because of insanity). It is up to the judge to decide and can not be speculated on.

Hello, I would like some answers on the rights of mental patients currently under treatment, recently I have approached a legislative councillor to request for an assessessment of my current mental state but was refused by my psychiatrist at East Kowloon Mental clinic as unrelevant.
On my recent visit to the clinic I refused to be administered with injection which I was regularly injected on a monthly bases, the medication subscribed to me was inappropriate for my conditions but rather for a much more serious psychotic mental patients. Can I be institutionilized or detained for refusing treatment if I am of no danger to myself & to others in society?

我諗你應該即刻去睇精神科醫生，係專科果隻，因為呢個係你唯一的生路。

樓上的學長已經說得很明白，法例有規定，犯案時假如你根本唔知自已做緊乜係可以作為答辯理由的。但知唔知自已做緊乜，唔係靠你自已講的，如果自已up就得，葉繼歡使坐30年？張子強使打靶？依d係要靠精神科醫生確認的。你果d社工、中醫全部都無資格作出咁樣的判斷。

案發時都未睇過精神科又點？精神病唔係一朝一日會發生既事，專科醫生可以講到你大約最初幾時出現咁既病徵，同埋判斷響案發時你是否受病情影響而犯案。若是，應獲無罪判決。如有睇開，就同醫生講番件事，叫醫生寫番個報告同傳召醫生上庭作供。

店鋪盜竊一般是裁判署案件，法援署不受理，應該係搵駐庭當值律師。你1月3日上庭。強烈建議你盡快搵律師，私家、當值律師都好，告知他你會以精神病作答辯理由，好讓他有足夠時間去向公立醫生索取詳細報告，因一般要成8個星期先會預備好 (咁私家就梗係快好多)。假如真有精神病問題，可向控方提出簽保守行為。

我認為你既罪名唔大，我認為你首先要承認你系偷過野，不過你當時系因食完藥而神志不清，所以系冇心盜竊。加上你患上肝鬱結和有幻覺的情況下，一定會輕罪。我建議你去睇下心理醫生，佢會開解下你
