Hi Jena - I believe your pain is real and I think you did the right thing by talking about it on this forum. There are so many loving and kind people in this world, so please do not feel confined to share your heart with just a doctor. They will look at you like a patient, whereas, someone like a Christian counselor or therapist will look at you like a beautiful individual with feelings, dreams, goals, and a search for purpose. They will not be able to offer you medicine, but they will offer you their listening heart.
You will feel better connecting with someone who will listen to you. You could start by calling around to some Bible believing churches in your area and ask if they have someone on their staff who is equipped to address people in your kind of situation, and perhaps they can offer wise counsel and better help you understand yourself.
Talking with someone you trust is self therapy and will pull you out of feeling isolated and defeated. We all need a lifeline every now and then, so please let others help you. There are so many things in my life I could not do in my own strength and needed to lean heavily on someone to help me.
In the meantime, make a checklist of things you can be doing to help yourself; such as, eating foods rich in niacin and magnesium, getting adequate exercise every day, eliminating all alcohol, sugar, chemicals, synthetic skin care products, processed foods, junk foods, and caffeine. Your body will have more mental fighting power when you are able to implement a proper diet of just fresh foods and exercise. There are scientific reasons how they are all connected to depression. If you would like additional information about how the mind, body, soul, and spirit of a person all work in unison, I would be happy to send you some.
Do not quit. Answers are out there - it's just a matter of connecting to the right people for help. You were created for a reason, and once you are able to see your own value, you can think differently about yourself and love you for who you are.
