My cat died in my arms

I’m so sad, I really like my cats. I just have this feeling that I have to move on with my life now, that I want to go out of my comfort zone, but I don’t know where. I feel so guilty because it’s so hard to feel guilty. I’m trying to be a positive influence, I’m trying to be kind, I’m trying to do good, but I feel like I’ve messed up with the wrong person. I want to go outside and be outside. I want to see the world. But I can’t because I don’t know where I go, where my cat goes. I’m just so confused. I have this feeling of guilt about what I have done? Why should I feel guilty about this? I’m trying my best to be a positive influence, but I just can’t. I know where I go, I know how to get to it. But I just want to go out, please. I don’t know where do I go?
