What's a good way to stop playing panic-y?

I have a habit where I tend to do stuff on shield or even just moves in general, and then I'll just roll/spotdodge/airdodge or something away. I don't really apply pressure that well because of this, I just end up getting scared or..something. I'll do a jump-in nair and because I don't expect it to hit, I'll roll away or spotdodge and I miss a follow up. Same can go if I do any aerial - if I do a jump in, people just tend to continue holding shield or read my roll because I've kind of grown acustomed to doing it.

What could I be doing instead? How do I stop myself from freaking out and just running away to reset to neutral? Part of it feels like I'm too hungry for the kill and I'm hoping for a whiff punish or something, but I can't be sure. It's a bit of a habit I'd wish to fix, and I'm not too positive on how to get over it.
