I am in the same boat, about to start my final year of psy. I want to do CP too!
Have you considered graduate entry medicine? It is very competitive but you may want to research this route just in case it's something you would actually love to do. You have really good work experience for it already, however if you didn't do chemistry and biology a-levels i can understand the route would be very long winded because you may need to go and get those qualifications before applying.
There is also a physician associate career you can look into. it is very similar to what a doctor does but the postgrad course is only 2 years and its much less intense.
Counselling psychology is an option and its also only 2 years.
Educational psychology is another one and it's a three year course.
Forensic psychology requires a masters and a three year course.
Other than that don't let how competitive clinical psychology is hold you back. Many people make it every year. If you really want to do it don't let doubts stop you.
Wishing you all the best
