Hi, I'm a 17 year old male and since a few weeks now, I have been experiencing brain fog and decreased concentration. I have headaches that come and go during the day. Sometimes I am unable to speak fluently and remember certain things. I just don't feel like myself anymore. Ps: I do smoke weed from time to time.

What's happening? Do I have a mental illness or something. I'm really fustrated and can't make sense of all this. PLEASE HELP
