about 4 days ago i began having audibal hallucinations. i am hearing the same song continuously. it isnt loud but it is always in the background. i am not using any drugs although i did use when i was younger, it has been about 6 years. i do however smoke and drink. i began hearing the song the day after i got laid off from my job, so i was wondering if it may be only stress related and if so will it go away on its own? i am hesitant to see a doctor because i am now unemployed and have no insurance, but if it might be something serious i would like to know so i can get checked out.
