Is It Normal to Feel This Way?

Assalamu alaikum everyone, I really need some advice... It's been five days since I started praying and learning about Islam. I was born Muslim, but I wasn't brought up practicing, so I've had to figure things out on my own. But these past five days, I've been hit with intense panic attacks, thinking I'm not a good enough Muslim, that I don't deserve to enter Jannah. I spoke to my mother (she's a revert) and she said it's the shaytan trying to stop me from worshiping Allah, and that I shouldn't worry because I'm a good person... but still, there's this feeling in my heart that's just eating me alive. Do all Muslims go through this? Or is it just me? Please help.
