Awwwww I feel a little jealous, I currently wonder what I should do, as my studies are rather interesting (but rather difficult) (I aim to have an engineer diploma in a little more than 3 years), and I never took time during my high school years to search artistic formations which I could like, because I thought that it wasn't worth it (moreover I had a friend who had the occasion to improve her skills so I felt outstripped, seeing her drawing so well ;u; ).
All of this to say, good luck
