We all fell depressed some time or the other. Mood swings are common multiple times in a single day, or perhaps in a single hour. But have you contemplated suicide? Not just as a passing thought but actually thought/planned of doing so?
If you have then you need to read this answer of Guruji:
Sri Sri Ravi Shankar on Suicide:
Q: Guruji, due to some worldly problems, I want to commit suicide.
Sri Sri Ravi Shankar: Absolutely not! Before doing this, come to me, seek my permission, then do it! I will tell you from where to jump and how to commit suicide. Don't make this decision on your own. I need you! Why are you losing your life? What do you need, tell me? Bread (roti), clothing, and a home? I am willing to give all that to you for all your life. You can just sit around. Have no worries and do my work. You will get respect, honor, knowledge, everything that you want. What is the reason that you want to commit suicide? You couldn't get married, that is why? Or because you got married, that is why? In both the situations, I will help you.
Don't worry. If you are not married, I will get you married. If you are already married, I will talk to your husband or wife. If they don't understand, I will advise you to take sanyas. Move forward. What will you achieve by committing suicide? Suicide should absolutely not be committed. All those who feel the slightest doubt or have such a feeling, immediately show them my photograph and tell them, 'Look, don't go without his permission, otherwise you won't get entry up there as well!' You will be hanging in between, neither in this world, nor in the other. Why do you commit such an act? First take permission, get the visa !
