I don't know what is happening.

Hi! My name is Alejandra and I have a very big problem. Recently a lot of purples spots appear in my skin and I have a horrible pain for my right arm. I don't understand why they appear because yesterday I only did my usually hobbies: I went to high school, I had lunch, I trained my super powers (go through walls),... It is terrible!!! When I went to school people looked at me like I was crazy. Today I tried to get on the bus using my superpowers and I ended up in hospital. My doctor said that I didn't have superpowers but I know that I can go through things. Please, help me! If you give me a good piece of advice, I will demonstrate you my powers. I send one photo of the wall of my bedroom.
