Is it normal to get sad and depressed when i'm alone and bored?

I literally cannot even spend a night in alone. I always have to have plans with people, because if I'm alone not doing anything I get bored easily, which ultimately leads to me getting very sad and depressed. When I'm not busy with people, I overthink little things and it just makes me so sad. If I can't talk to anyone or do something with people I just get super depressed and bored and I cry a lot and I panic and just overall feel awful and sad. I have to be busy and have plans with people every night.
