Hi... Depression and suicidal thoughts are quite high in young adults and working professionals but that doesn't mean it is okay to ignore them.
Sometimes it builds up due to some constant stressor (work deadlines, examination/academic stress, peer pressure, martial/Interpersonal relationship concern, etc.) but the root is usually deep down inside.
Psychotherapy/Counselling will help you identify the root cause of your condition and will help you overcome it in a longer plane of time.
If the intensity and frequency of your suicidal thoughts are high, I suggest you take a Psychiatric Consultation. Medication helps in suppressing these suicidal urges with immediacy.
Medication and Therapy go side-by-side in such cases to prevent any negative consequence.
Next Steps
Take a Psychiatric Consultation and start taking Counselling Sessions from a Psychologist.
