My deck never tells me anything helpful

I’ve been reading for a few years. But when I read cards nothing good ever comes out. I can read well for others but when it comes to myself it’s always negative or a warning.

It’s actually discouraging- I’ve been considering putting my deck down. I’m self aware enough to know my darkness. It’s not as though I carry a negative energy, my guides never communicate with me or even tell me anything positive. When it comes to others it’s spot on and completely different things I pull. I just don’t understand what I’m doing wrong.
