Discharged, U5 got marked, got hired (and let go because U4/U5)

I interview for a Financial Rep role in January, on my resume I had an expected graduation of the summer time. The start date wasn't until 7 months later. Long story short, my parent passed away and I took the semester off and deferred my graduation. I told the interviewer that I would not be graduating on time and it would be pushed back. Everything seemed fine, especially since the role did not require a degree. 

I start working at the BD, pick up a couple licenses, and then HR asks me to verify that I have my degree. I tell them the above and a couple days later I get terminated with the statement on my U5 "Concerns about accuracy of representations in the hiring process. Not sales practice or client related."

I apply for jobs non-stop, I get picked up by another big BD, I start studying for my final license meanwhile my U4 is undergoing review. The firm tells me today I have been terminated, (assuming its cause of discharge).

I feel a tad bit deflated and worried about my future of being picked up by a firm in the future. Would appreciate any advice, please be honest.
