I agree talking to a friend is great if you have one that can listen. I know that here in Canada we have and it is quite new I think but there is a number to call to connect and talk to people in the same situations and it runs 24/7. Night time is usually the worst time if someone is depressed nothing to do nowhere to go and can't sleep. Go figure by the time you get tired enough the sun is coming up.

Talking to your friend is a good idea. But honestly it takes a lot to do and I am working on it myself is physical activity. It emits endorphines and lowers anxiety. Also a tip I learned is that when a person is anxious or depressed Vitamin B12 can help control depressiion I am not sure how it works but it does...If any of these ideas helps that great and if not you may need to take some antidepresants. Alot of people going through this experience are on them and it is not permanent but it can help...
One other piece of information I was given and it helped me and again the "queen of anxious" was to concentrate one day at a time and even better one moment at a time. For the moment this moment I am ok and when you start to get worked self talk yourself. It connects into a whole line of meditating and self talk. There are many varieties of it. Mine was to be totally aware of my surroundings start off with 10 things I can hear right now and feel right now. Then nine things I can see right now hear right now feel right now. You get the idea and do this all while focusing on a rock or an object (necklace, stuffed animal whatever). The more you work on this technique as soon as you pick up the object you will automatically feel safe and calm. It worked for me I have a necklace I used with an amathyst crystal.

Anyway sorry to have rambled I know how you feel and want to help you get through this. You can and will. One step at a time!!! Lean on whoever is willing to let you!!!
