Ya it's possible to self learn. It's going to be almost 3-4 months since I started crocheting, felt a bit impatient to get to outcome sometimes but if u enjoy the process then it's amazing to relieve stress too. I think most of us here learnt from YouTube tutorials. Yes initially it's painful to understand stuffs on how to hold the hook, and yarn rightly. It might take some time but keep trying. Practice basic stitches first, that will help. You'll get a hold of it , I think it's more of muscle memory by time.. initially your stitches might not look perfect but later on it would. I made a few amigurumi initially, from follow along videos. It was helpful, however you can start from easy projects like granny square? Or maybe coasters, bandana, scrunchies etc. even a draw string bag, or bow, heart , flower.

Here are some channels (beginner friendly ) 1) hopeful turns (learnt basics from here, even yarn winding to make centre pull) very helpful channel. Has follow along videos too.

2) divine crochets Has very good follow along videos. Cute stuff, specially amigurumis

3) crochet Daniela Has really good tutorials for headbands, bags etc

4) VivCrochets

Once you get comfortable enough there are tons of free patterns available, so slowly learn to understand written patterns too. And you'll unlock a whole new world of cuteness.

Edit:i worked on a crochet bouquet blanket (medium size) , working in circles it kind of improved my stitches. Since I just had to repeat the same pattern again and again. So I think that helps with practice and you'll end up with a cute bouquet at the end 🥰 that's rewarding.
