Share with family and friends
When feelings of uncertainty in life surround you, be ready to share them with others. Life always has someone prepared to listen to you and give you words of encouragement. Maybe those words of encouragement will be the motivation to lift you up now. What you are experiencing is definitely something that someone has experienced. An objective outside perspective will give you an objective voice.
Usually, however, people tend to want to hide the difficulties they face. Your outer appearance is still excellent, but inside there are many problems. You can choose to read about the autobiographical lives of celebrities and politicians to see if you can learn anything. Articles like this abound, both in print and online. The best thing right now is to find someone with experience. Ordinary human psychology is to love to teach others, so don't be afraid to ask, they will answer more enthusiastically than you can imagine.
