Hi. Considering the fact that you have suicidal thoughts, you should immediately seek help. You should consult a psychiatrist without any delay and initiate treatment. Also talk to some your family members and inform them about the same.
Since your symptoms are present only for 5 days, it is highly likely that it would be a response to a stressful life event. Discuss regarding the same with your psychiatrist as well as a close family member/ friend and vent out your feelings.
Best wishes.
Next Steps
Talk to a family member and seek a psychiatric consultation.
