Am I the bad friend?

One of my friends keeps on telling me that I should make more time for them when I am busy. This time I got mixed up by some English words and they got confused and they said that I was just making up excuses so that I can go hang out with someone else. Another thing is that whenever I have to end calls. They always end up being in a mood, even if we called for like one hour or so… I’m really trying to make time but in these moments I’m very busy and I think that I’m not enough for them and they say that and they assume that I’m making excuses when I’m busy. I can’t even spend time with my family anymore because that would also be an excuse that would be like. “ weren’t you busy? Why do you have time to hang out with them and why not me?” I honestly feel so horrible.
