I've got an option to stop doing presentations in front of my class. But I don't know if it's really good for me. Hi! So firstly, I wanna apologize for my english. It's not my native language. I'm 18 and I suffer from depression and anxiety. Last school year was really tough for me and not just because of stutter. I study at a school that can be considered hard and was supposed to do many presentations in front of my whole class. My classmates were laughing at me a bit and I just couldn't think clearly. My heart was beating hard, etc.. I suppose you know the deal. It came to the point when I was too afraid to go to school and started failing in some of the other classes and was having problems because of my absence. I made the exams just because my professors were too kind to help me get through. Now the new school year has started and I also begun to visit a school therapist. When I told her about my problems, she offered to help me, that she would let the professors know that I shouldn't be doing presentations with a severe speech impairment. And here's the problem. I know I should fight my stutter by going to grocery stores alone and so on.. But can this help me too? Grocery store with one person is one thing but a presentation in front of a whole class is on a whole another level. Does it really help in the long run? Thanks for any ideas. I really appreciate it.
