Be forgiving and patient with yourself. It is all right to make mistakes or lose your concentration. Be good to yourself. Take the rest you need, the walk you enjoy, the gift you would like. Give yourself time.
Time does heal, but how long it takes is an individual thing.
Seek guidance from a source that can offer you both wisdom and empathy. Numb your pain with depressive chemicals such as alcohol or other drugs. Deny your feelings. Expect every day to get better. Accept ups and downs.
