So, since some time I noticed, that when not doing something that occupies my mind or just being tired, I'm having those thoughts that make me really anxious. They are uncontrollable, but 100% inside my head and I know that they are not real,  I'm still afraid that it might be something related to schizophrenia tho.
The thoughts randomly pop in my head and disappear right after, most of the time they are my voice or in voices of people that I heard/talked with that day and they make no sense, like those are random words, some examples "infrastructure", "yes", "I'm here", "Whatcha doing" etc, nothing that make sense.
I'm really anxious about them and I don't want to lose my mind, I'll add that I can't visit a psychiatrist soon because of money issues.
Do you think those are serious symptoms? Or might it just be slightly normal/anxiety/adhd related (I don't have adhd but I really suspect it)
