During any stressful circumstance, especially ones that deal with family members, it can be very difficult to cope. This is normal. It is certainly very scary when a close family member is dealing with serious health issues. The most problematic thing, in your case seems to be the total lack of control that you feel you have. No, you can't control the health or future of your father. This can be a very difficult realization especially when you normally feel in control of everything in your life. The truth is, we have no control over the events that happen in our lives. What we do have control over is how we deal with those events. This often times helps me deal with situations in which I feel out of control. The health of your father's heart is something that you cannot physically control. What you can do, is control how you react to the situation. You can let the stress and anxiety get the better of you, or you can turn those negative thoughts into positive actions. Look for the opportunity in negative situations. Look at them as a chance to grow.
No matter what you think, stressing out does not give you control over the situation. You are actually placing the control in the world's hands if you give in to stress and anxiety. Take claim of your self and don't let the anxiety get the better of you. You cannot control how everything turns out. Bad things happen to everyone. The important part is how you deal with these things.
I just saw a touching documentary about a young woman diagnosed with a serious form of cancer. She did not accept it as a death sentence. She looked at it as an opportunity to get the most out of her life. It was her wakeup call to start taking care of her body. In some ways, she considered it a blessing because it really made her aware of her mortality. Even though she had a fatal disease, she was a happy person who was making the most of the life she was given. I though this was a great example of how positive thought can change a situation.
I hope this was helpful to you.
I know stuff is hard, but just try to remain positive.
