Bouts of sadness

[sanawana]

Hi, I am a very melancholy and sentimental person and sometimes I fall into a state of great sadness. I thought it was normal and that's my character, but someone said it might be depression. What do you think about it? This condition is not ordinary sadness, but a great pain. It is an unbearable state and in such moments I dream of being able to talk to someone, loneliness is unbearable in this state, and the normal state of loneliness does not feel a burden. I believe that this deep sadness most often comes when I'm afraid of losing something very important to me. Do you have any ideas how I could overcome this sadness?
