Of course you are angry! You have every reason and right to be. Your boyfriend is not helping, and he is affecting your life financially. This is your family's welfare he is messing with!
And it is perfectly OK to love him and be infuriated with him!!!

Please, though, do call your doctor. These meds you are on might be making it worse. And they certainly are not helping.

You need to see a psychiatrist for psych meds, not a regular doctor. It just works much better that way.

Have you considered couples therapy?

It sounds, imo, that your boyfriend is depressed. He may need some medication as well. Have you talked to him about this?
