Depression?

Okay so for the last past 2 weeks I haven't been feeling myself at all!! I am very emocional I cry a lot I feel sad, I don't feel in the mood for doing the things I normally did before. Sometimes I just want to spend all day in bed I just wanna sleep sometimes I don't even want to eat I always do eat just not as much as I know I need to. And this week I just feel tired and sleet but when I get to bed to take a nap I can't fall asleep I can't sleep at night. I have a really hard time falling asleep I literally fall asleep at about 4 am every night and I will be up at 7 am in the morning. I really don't want to feel like this anymore HELP!!😞😞😞
