Sorry to hear about your loss. It is a huge loss and requires strength to cope up with this. You may feel angry, upset, guilty and low on confidence. No matter how hard it is, but like in the past you have been able to move out and cope up with things, remember that you are the same person wth the same strength, you may feel weak at this moment but the strength is within you. You need to just gather all the strength and bounce back. If you feel, seek a help of a counselor who could help you sail through this phase more effectively. Strength to you. Best of luck.
