Are you qualified to apply for the Quality Migrant Admission Scheme launched by the government few days ago?

If you want to stay in HK, why you don't take a risk to travel to Macau and then re-entry again... at least until you fail... I think they will allow you to get back your stuff in HK under the human rights. So why not take a chance?! That's what I think.
Of course, you ultimately need a job to sponsor you to stay here. Is there any network here that can help you out?
