Sorry to hear you are having difficulties 😔 now, on the face of it...this may seem like a weird suggestion but bear with me...
Would you consider having a feng shui report done on your business? I place I used to work at had this done and it made such an impact it was amazing! A person qualified to do such a report will advise you how you can improve the flow of energy within your establishment. There may be something causing negativity that you are not aware of that it causing your business negative events... Staff issues, client issues etc.
You may think this is all a bit airy fairy and a load of nonsense but I have seen it work first hand so please at least consider it. I know it will mean spending money within a business that is already struggling but it could work for you. Just another point of view.
A quick tip to get you started... Get an amethyst crystal and place it on top of where you keep your client record cards...amethyst incourages things to increase, so on top of your client filing cabinet is fab but on top of your invoices is not 😉
FYI... I am not a feng shui specialist in any way, I just believe it works.
Good luck x
