Hey woj,

I'm so sorry about your pup. You know, my dogs are my companions, my soulmates, my kindred spirits. They're so essential to our joy and well being (especially mentally) it's no wonder you feel so lost and full of grief.
I have felt the same (yes, over an animal) and there is nothing wrong with it. Honor your dog and honor your feelings, feel them and talk. Our animals give us SO much and it is a HUGE loss when they leave us. I understand completely.

Grieving is one of the hardest things we ever have to do. Every time I've felt it, I thought I was going to die from the emotional pain. I'm so sorry about your loss, it may not seem like much to say, but it gets easier, it really does.

Are you seeing a therapist by chance? A therapist could definitely help you cope with these feelings. If you're not in therapy, I would suggest trying it out.
It sounds like you're going through some huge changes, what with quitting your job and leaving your girlfriend. I just want to say that you're not alone in this.
I've been there and have felt completely full of fear. Keep coming here and talking with us, you're not alone.
