Online therapy is a good option and costs less. I've been doing it for the past three years. I find it very helpful. I have my own room to post in when ever I need and my therapist responds 5 days a week.
I'm sorry to hear about your family. I can relate. I feel lonely often and I feel like my family is giving me the silent treatment. But I figure they are just busy with their lives. Yes, it hurts that they aren't more thoughtful. But I know it's not intentional. I make the best of it so I feel better. I think that's great that you're a vet tech. Sorry it's so stressful. I hope things get better for you. If you ever need a friend, just PM me. I'm hear to listen.
