In times of distress and worries, it become difficult to focus on life's important priorities and to choose what is good for us. You seem to be occupied with so many life's problems that it is becoming difficult for you to focus on yourself and your personal peace of mind. When mind becomes too much occupied by external demands and responsibilities, other than self, then it becomes difficult to focus on oneself to maintain relaxation in mind. Therefore, what you need most during these times is to find some time for yourself and meditate or introspect and see what you want most for yourself in life and how your current activities are going to make it happen in near or later future. This will help you in centering yourself in your mind and you will get clarity into what you are doing and why. You are doing what is right for you at this moment but you are not doing it for yourself so it is becoming difficult for you to aspire for it completely. This is building frustration in you and you are getting irritated and anxious.

To understand and to handle your problems,  do consult a psychologist either online or offline.

If you are not able to tackle the problem & if it has persisted for a long time, affecting your day to day functioning, then you can visit a counselor who can suggest ways to improve your coping about the situation.
