Welcome MrJames! No, you do not sound ridiculous or bratty. In fact, I had some of those same feelings months after I quit. That's the great thing about SR - we usually find others who've felt the same way we have, even though we're sure we're the only ones.
I hope talking about it will relieve some of your anxiety. It certainly helps to have others to discuss things with. Sugarbear & Instant both have good suggestions. Glad you are here to get some help.
