Hello, For the last few weeks, I feel like I ve gone insane. Several weeks back, I thought I heard my friend say my name at swim practice. He didn t. Since then, my mental health has seemingly gone downhill fast, and it has worried me so incredibly much. Every time I hear a noise that I don t know the source of, I have gotten really scared. But, I figured I was just being paranoid about it. But, recently, particularly in the last few days, I ve had random thoughts just pop into my head. I don t know how to explain it, but they re soft, and they re not mine, at all. For instance, I was reading a article a few hours ago, and the word communists just popped into my head. Just the word, nothing else, and it seems as if I didnt think of it. It s like having auditory hallucinations, but you don t hear them, you think them. In the last few weeks, I occasionally would have one of those random thoughts once or twice a day. But today, I ve had countless. At the same time, I ve had ringing ears. I ll turn my head, and the ringing will stop. It scares me, and I think I m going crazy. Today, I also heard beeping in my ears, and what sounded like construction. And, whenever I think or reflect on the ringing in my ears, it comes back again. So, am I developing schizophrenia, have I gone completely insane?
