It is common for teenagers to worry about mental health symptoms but it is not common for teenagers to experience the symptoms you have described. They are concerning.
One example is your thinking about the spider web. Others simply see a spider web whereas you see evil divided into eight sections. You seem to be imposing supernatural ideas onto normal, everyday things. There is nothing demonic or evil about spider webs.
You mentioned having visual hallucinations but you didn’t describe them. It’s possible that you are describing daydreams but, generally speaking, visual hallucinations are uncommon. The physical sensations you have experienced are also unusual. These symptoms should be brought to the attention of a mental health professional.
It’s good that you are able to communicate with your mother about your symptoms. Your symptoms are obviously distressing and treatment would help. Your next step should be asking your mother to make an appointment for you with a mental health professional. If you or your mother have any additional questions, please do not hesitate to write. I will be glad to answer any questions that you may have. Please take care.
