I am a little older (OK about 15 years older) and I still have days when I wonder when I will start "adulting". There really is no such thing, I have come to realise this and embrace it, I am who I am (an anxious mess some days, a rational professional on other days)
There are so many expectations that we think we are meant to achieve - , buy a house, have a family, get your drivers licence, get a good job etc. These put a lot of pressure on people of all ages, especially younger people, because you put more pressure on yourselves than we ever did.
I bought my first house 2 years ago, at the ripe old age of 48. A friend of mine has had her learners permit to drive for 30 years, and wow can she navigate the public transport system, it's incredible, she decided she didn't need a car, so it took the pressure off her to get her licence.
As for your creative side..... this is the future, creativeness, film making, 3D, animations etc. Please don't let anyone tell you that this is not a good path to take, it is the future of our jobs and if you feel naturally drawn it to, maybe consider looking into it - it changed my life (I'm still an anxious mess - but now I sit with my noise cancelling headset on and work making things come to life)
I recently changed careers (mostly due to that horrid year that is 2020) I am now working from home, creating 3D animation interactive video for corporate workplaces and my clients love it, I am creating their workplaces as walk through 3D worlds.
I have always loved this type of work, but I have been too scared to test my skills, it all looked very hard, and I kept doubting myself and my capabilities, but I stuck with online tutorials on how to use the software and create this material.
I love it, and I have a lot more freedom, I still have days when my anxiety hits (that is what my noise cancelling headset is for - I play soft music and the world around me disappears and I start creating.)
Lastly, I am so happy for you for getting out of a toxic job, and for recognizing the need to do this yourself and to focus on your well-being.
Best of luck - Pip20 :-)
