I have been noticing signs of separation anxiety ever since 2021, I ignored them but eventually they showed up again. I was anxious about two things: My friend leaving me and the possibility of my dog dying. 

My friend and I did eventually broke the friendship and I'm fine with it, hell, even better than then ( or so I think ) , but one problem remains, my dog.

My dog's health is very slowly degrading. Shes 15, shes slowly losing eyesight, her tumors are spreading, and I'm scared as fuck. I'm very anxious and feel guilty whenever I go out with my friends because I canr spend time with her. I feel guilty for leaving her alone.

I wish she could live forever, but that's not going to happen and I'm sad, scared and frustrated.

How can I ease this fear?? It fuvks me up and I want to spend time with her without thinking about her possible and inevitable death because of old age.

Thank you
