It's normal for an IT employee to get stressed due to work after a few years of service. Since you are an experienced employee, you can take leave and go for a family trip or have a break for a few days. You can change your job if you still don't feel the same.
If you can balance your work life balance then no need for a psychologist. It's better to go to a psychologist if you are facing major tension, stress, and tiredness.
