Orgasm troubles…

So my bf and I have a great sex life but here recently I haven’t been able to have an actual orgasm in about a month. I’ve tried getting myself off a couple times and still nothing. I don’t know if it’s my depression that’s causing it or the medical problems my dad is having. I’m afraid that my bf is going to lose interest since he’s the only one actually enjoying it and he hates that I’m not getting any sort of pleasure from it. Does anybody have any advice for tips? I’m desperate at this point and willing to try anything
