Thank you for writing and telling us about yourself. You are not alone in your feelings. We'll do our best to help.
Fearing the unknown, such as about your companion dog, when you are doing your best to care for him, only hurts you and him. Yes, billions of other animals are suffering and dying every year at the hands of uncaring and hard of heart humans, but you can take a positive stand against these evils, and feel good about yourself for being able to help, even if in a very small way, such as not eating them or wearing their skins.
This is all part of turning the energies you put into your depression into actions to help end the evil in the world around us. This is what we've been doing for nearly 30 years.
We can also help you with becoming vegan without the problems. Sometimes the sickness you described in because you are removing toxins from your system (withdrawal symptoms). What kinds of vegetarian foods did you try?
We look forward to hearing back from you.
In the Love of the Lord,
Frank and Mary
