They cannot answer that question for you, how can they know the real reason you harm yourself. It is not the same reason for everyone.

I self harm and don't understand fully why, mostly I think its the need to escape my reality, my hurt and pain. Misdirected frustration. To be admitted and looked after. Sometimes I didn't remember doing it just woke up in hospital my motivation being subconscious. Alcohol lowering my inhibitions is a major factor it took me a long time to accept the role of alcohol in it. That's why I do it as far as I'm aware today it may well be after I go to DBT I will understand it differently.

To get the answer to that question you need to reflect internally, examine your cycles of behaviour. Mb accept some harsh truths about the situation so requires you to be humble and honest. It's amazing how well we can lie to ourselves.

Your mental health team can support you but not do the hard work of self reflection and realisation. They can teach you the tools like meditation, listen to you ask you questions to make you think.

I have also struggled with mental health teams feeling that they did not know what they were doing, they just felt disillusioned and uninterested in their role of support.

Have you told them how you feel?

That you want more from them, ask them why they won't explore difficult questions with you? It may be that they want you to come up with the answers yourself. This is a popular therapy tool which drives me mad also it prevents the worker from entering a conversation they can only paraphrase what you have said. This method should be abolished it really makes my blood boil too.
