Depression can be crippling, as I know having gone through it myself and having no one to console me. I find it can be very hard to share about it or deal with it in general but the best thing you can do is open up about it and reach out to someone that will hopefully help you get through the tough time.
If your lucky you will have friends or someone that knows you so well they can tell without you even having to ask that makes things a lot easier when someone starts the conversation for you and checks on your well being.
That is true, opening up and expecting a listening ear or a shoulder to lean on is a healing. It is also good when people discern and offer help. I hope you are feeling better yourself
