Hi, Joe;
Glad to see that you're talking to a mental health provider now. Is it a therapist or a doc? You may need a prescription, and that's the only reason I ask. Yes, you do sound like you're going through a really tough time.
There's a few things that help me when I'm down. Exercise. Yea, I know you don't feel like it. Force yourself, you'll like it afterwards. It releases endorphines, a "feel good" neurotransmitter in the brain -- all natural. They do help. Try to eat right too. It can really make a difference. If you're not eating right, take some vitamins until you can get your act together to do so.
Learn something new. I know, I know, it's really hard now. You're mind wanders and you can't concentrate, right? Well, no one said to learn rocket science, lol! Just take it a step at a time. What have you always wanted to know? Or to learn? Each day, spend a little time learning something.
Practice positive statements to yourself. You are a child of G*D. Remember that. You have everything you need right now to do whatever it is you are supposed to do and be. Stretch yourself. Learn your worth.
And be grateful. For what? you say. For the fact that the sun always rises again. For the fact that with each sunrise is a new opportunity. What is there in your life you are grateful for? Don't look for the mansions and cars and material goodies eveyone thinks they want. Those things never bring happiness. Look for the everyday miracles in our lives.
Finally, pray. Or meditate. You say you have a religious belief, so, get in touch with the G*D of your understanding. Recognize that spark of the divine within.
I'm sorry you are so down right now. It seems as if it's been for a long time. So, there is no "quick fix." It's a one day at a time thing here too. But, if you keep on doing the next right thing; take care of yourself physically, mentally, emotionally and spiritually; and get help from your doctor, well, it will get better.
And we'll be here each step of the way. One day at a time.
Shalom!
