You do get eventually over a loss.
At first, you may go through denial, like someone is trying to pull your leg, or no way that the person you knew/loved is gone, they can’t be?
then the grief sinks in, it can last weeks, months or years, depending on the person and your relationship with them. You’ll see them in every little thing that ever related to them, some memories will make you happy, others will make you sad.
Then acceptance, it’s the way of life unfortunately. You’ll live on, them in your memory. The reminder of their absence will become lesser, and it will be less bittersweet.
just remember it’s okay to cry on someone’s shoulders, don’t mourn by yourself, it can be worse that way
