I Have Anxiety

I have negativity as well, anxiety is the main cause though. Do you know I recently spoke to a lecturer to ask about there being any corrections required on my recent first draft of my science report. I thought due to the fact I am sending it away as my final. I was anxious things might need corrected. But my feedback was already given approval. I however always doubt my abilities. She said my report was a successful one. I get anxious!. And in my other class, the same thing...an experiment report. Got given great feedback. But, I still arrive wondering what could I have done better?...as we approach the practical I'm nervous inside. Im doubting my abilities. This could be due to the epilepsy I have which does influence the nervous system, or the discrimination I've faced due to my identity. A lot of positive feedback is overlooked and I'm always predicting the worst case scenario. Like when a customer at my work once said my name to a another colleague, I looked up thinking I was in trouble for bad service....turns out I was being complimented for good service. And yes my medical which sometimes has me falling to a seizure, has me thinking im useless and perhaps unnecessary to my workplace. The documents say different. That with my years service I'm one of the top assistants at the front end....How do you turn negative thinking into a postive style of thinking?..it's been my way of thinking for some time..but then??..my gran was always seen as pessimistic?...maybe it runs in the family 🤔
