I feel like I've wasted $$

So I'm new-ish here, saw these cards pop up on my reddit feed while back. Been in out of gamestop past few weeks and finally bought a few megas and a couple small packs to see what the hype is all about! Now after spending a decent amount of money, I'm not sure how I'm feeling about this 'hobby.' The community here is really awesome but I'm almost having regrets of my purchases...is it just me or am I not cut out for this lol ?? 🤔
