i think it's just new to you.
it took me a long time to realize that i actually have feelings and emotions. and i will have really sh..ty days and freaking great days.
getting in touch with your feelings can be a little scary. i'm still often confused by these strange "feelings" that are actually pretty normal for everyone.
i wouldn't worry about PAWS or any of that stuff for that matter. half of it is made up anyway (yeah that's my opinion).
exercise, eat well, and don't read too much negative stuff on the internet
