You can go to uni as a mature student at any point in your life
My DS will be going to uni in sept
DD when she finishes her A Levels wants to use her free paid for year of education at our local college doing a foundation course in a subject she loves. She knows it's not worth doing as a degree. She's not entirely sure what degree to do and not currently confident in how she'll do in her A Levels
DD works PT and they are very lovely to her there so she'll work and save (and spend)
OP you are young so you have time to explore and live your life
You can do an access course later on in life and go on to do a degree using that
Nothing you do now will be a mistake. Don't have regrets. Take advantage of any opportunities that come your way
Be confident, believe that you are capable of anything and don't let any doubts hold you back
Do not ever let a relationship hold you back
You are a strong confident capable woman
You have time. Apply for roles you want even if you don't think you'll get them, you really never know
How about choosing a degree you love and then doing a one year conversion to become a lawyer and then apply for a TC training contract
You can travel in a few years if you haven't found your passion or there's a suitable break when you think ok I'm ready. Thailand is easy and safe to travel and if you go alone you'll meet loads and loads of similar people.
The Islands like Ko Tao will be perfect for you
