Can I be fired for cussing while talking to my security manager?

Question Details: I'm a security officer and my manager had called me to remove me from a post. I tried to explain to him why I was late because I wasn't paid enough to able to pay for transportation to get to work. I got a little mad and I raised my voice a little and told him to go ahead and just remove me, then I hung up. Then 5 or 10 minutes later he sent me a message saying, "As of today you are suspended until further notice due to your behavior and demeanor towards your manager. I am requesting a sit down with our HR manager". I told him, "I never said anything or did anything to you so". I tried talking to people above him but they seem to be on his side 100% of the time. My boss never seemed to be cool with me from the beginning; he is always trying to put pressure and me and telling me that "if I can't handle the job to let him know and he will find someone to replace me" which I can handle the job I just don't make enough to do thing how I need to in order to be at work on time I literally live in a hotel and it seems like my boss just wants me to quit my job or is trying to get me to quit my job. I don't know what I can do to fight this.
