I'm mentally depressed due to love. I was a best relationship with a girl as a friend. We are very best. She is a love failure girl but not Me. After few days over I'm affected to love on herself & I told my love & also I'm new to love. But she is not interested to marry but she told no objection to continue the friendship. Now I couldn't concentrate on my work, studies everything. But we are talking as well as at first. Everywhere every time I'm thinking about her. Also I'm watch many YouTube channels, reading many notes to recover myself but I can't. Now what is the standard & correct thing to recover myself. Please say I'm very very disturbed.
