Hey Katrina.
I can't understand personally what you are going through because I'm only 17 but I can relate to having nobody to talk to.
It's real tough.

but don't lose hope. When I feel alone, I talk to myself. Sounds weird I know, but what else do I do, hold stuff in?
Try to remember how blessed you are to have a home, a husband, a beautiful child. Thank of all the things you are personally blessed with that many others might not be.
Don't let the little things get you down. Notice how your baby smiles or the sun shines through the window. Read some good books, listen to music. These are things that can help you feel better.
Remember that we are all sent here to have trials. To grow from them. Heavenly Father has not forgot you. Ask him for help, he will give it to you.
Talk to someone who has no friends too. You'll have something in common. Write in your journal. Talk to your 9 month old. Write your husband letters.
Do anything that makes you happy, do not hold your emotions in.
Read the scriptures, they have great guidance in them. The people in them were blessed for how they dealt with hard times. You can get through this. It takes time.
Never forget how special we all are.
