Why am I getting cycles of depression?

Namaste Aditya Ji, The cycles you speak of are the literal movements of the Moon (Chandra) and Mars (Mangal). Born on September 9, 1991, at 4:55 PM in Lucknow, your chart shows a sensitivity to Lunar Transits. Every month, when the Moon enters your 8^{th} or 12^{th} house, your "emotional tide" goes out, leaving you stranded. Because these episodes repeat every few months, they are likely tied to the transit of Mars, which creates "Manasika Jwara" (Mental Fever). You can expect emotional reprieve when you build an "inner dam" to manage these tides. Astrology is your weather forecast; now you must build the shelter. Remedy & Problem Solution: ● Chandra Yantra: Install a consecrated Chandra Yantra in your North-East corner. It will stabilize the "cycles" so they don't hit you so hard. ● Meditation on the Tithis: Track the Lunar calendar. On Amavasya (New Moon), be extra gentle with yourself. On Purnima (Full Moon), engage in charity. ● Shiva Manasa Puja: This is a mental worship of Lord Shiva. It is the best remedy for those whose depression comes in "episodes.”
