Let us not pathologise things firstly. Yes, there are many people who stare and many who stare back and most of the times it is just normal. I know it is very much against 'our' culture for a lady to be staring or even staring back. But, how much pathological it is to be called a problem or illness.
I suggest you need to start focusing your gaze on things rather than people and make an active effort to remove your gaze from people to other objects. Besides, if you make eye to eye contact do not hesitate to have a slight smile on your face. Besides, you need to probably work into making more friends, spending time with them , improve relationship with you hubby, engage yourself into meaningful reasonable activity according to your interests and start enjoying life as a whole. Remember, marriage is an institution and each one needs to keep on working on it to make it successful. It is normal for mind to waver, but it is rational to organise it and focus on positives.
