Stress and Anxiety. From my family!

I have been experiencing frequent pain at the back of my head, which feels like it is inside my head. At the same time, my eyes often become dry, and I also feel weak and low on energy. I have been under a lot of stress and anxiety because of pressure from my family regarding my studies, exams, career, and future responsibilities. I often feel that my family does not understand how much this is affecting me. They keep asking me when I will clear my exams and tell me that I need to do something because my father is getting older. Because of all this pressure, my mental and physical health has deteriorated significantly. I often cry alone and feel emotionally overwhelmed. I have also been having suicidal thoughts. I am 23 years old and the only son in my family. My father is over 60, which adds to my anxiety and sense of responsibility. I would like a proper medical evaluation for both my physical symptoms (headache, dry eyes, weakness) and my mental health. Please guide me regarding
