The cloud will move away and things will get better. But not as fast as you want it to. You came back from a very dangerous place in your life. And those who love you really appreciate you in their lives more than ever. You will even grow closer, if you let it happen.
If you feel that you are depressed or if you occasionally feel suicidal - don't wait for it to get better. Get help from a professional, even if it means going to the emergency room. A professional psychiatrist or psychologist will talk to you, get to the root of your problems and give you advice on how best to address your depression: through medical, therapy or other activities. While it may take time to get better, it is better to take control of the situation now.
