@Captain24 honestly hun (and I hope this doesn't sound invalidating) what you're describing sounds super duper normal to me. It's okay to feel lost, to feel like you're going backwards, or to struggle to be putting new skills and stuff into practice. It doesn't mean you're failing or that you're not making any progress. The fact that others have already noticed a change in you demonstrates that you are totally making progress!
Frustrating as it is to hear, making enough progress to notice a sizeable difference often takes months/years. It's not really something you notice day-to-day, at least not in my experience. It's more like... after a while you look back and go 'wow, I am actually doing really well... thinking about a year ago when x/y/z was happening, I'm actually thriving in comparison to then'. But that's not to say you can't have big epiphany moments and distinct moments of growth, just that largely, it's incremental, so sometimes it's about looking at the bigger picture than focusing on the struggle of day-to-day. You only got out a couple weeks ago after all!
Me, I'v been doing okay, though today has been kinda crappy. Someone side-swiped my car (it was parked, I wasn't in it) so now I got a big scratch, I'm so peeved. How's today unfolding for you?
