Hi
It sounds strongly connected to health anxiety and overthinking that became more intense after emotionally difficult experiences like your grandfather’s death, your
thyroid diagnosis, surgery, and your classmate’s death. When anxiety becomes health-focused, the mind starts constantly scanning the body for danger. Normal sensations, dizziness, weakness, or minor symptoms begin to feel threatening, and the brain repeatedly jumps to worst-case conclusions. The more attention you give these fears, the stronger the anxiety cycle becomes.
Your symptoms are real, but the constant fear around them seems to be increasing your distress more than the illnesses themselves. Therapy can help you break this cycle of catastrophic thinking, body-checking, and fear-based overthinking so you can feel mentally calmer and safer again. Take therapy.
