Denied from Paramedic Science??

I got an email saying I didn't receive an interview nor did i get on the waiting list for one and I'm beyond destroyed, properly broken but I'm wondering is that me now just fully denied or is there a slim chance that i will get the opportunity to get in or do i just have to redo the full process

Are you saying the one specific university (Ulster University?) decided not to make you an offer, or that all the universities to which you applied did?
If they all declined to make you an offer, and you used all five choices available to you, then you can apply to one more university via UCAS Extra. If they don't make you an offer, you can apply for one more. You can keep doing this until UCAS Extra closes on 4th July.
If you still don't manage to secure an offer, you can apply via UCAS Clearing once you have your results. That applies to Ulster University, actually, if the course is in Clearing.

Only one available for me for paramedics in UK is Ulster and im pretty set on that

Well, unless it happens to be in Clearing on results day I think you need to consider it no longer an option.
In recent years, they've only made offers to 3 in 20 applicants, and the lowest grades they've accepted have been BBC* - so it's clearly very competitive.
* The stats which UCAS provide (here) exclude the bottom 5% and top 5% of applicants, to avoid statistical anomalies - so there may have been some below BBC in that bottom 5%.
