I'm going to echo what somebody else said in that time is ultimately going to be the only thing that really changes how you feel. Which I think is what we really want when feeling this way. For me, I got high and did my best to detach from life by deciding feeling nothing was better then feeling horrible (which I don't recommend doing).
It took me a long time and lots of therapy to realize how important it is to feel our emotions when we feel them. Cry if you feel like it, scream, or even punch a pillow. Don't run away from what you're feeling because you can never escape it. Feel it now while everything is fresh so that you can work through those feelings in a healthy way.
What is a healthy way? Well that's different for everybody. All you can do is keep experimenting, researching or hiring a therapist to help work through it. Friends can only be an ear for us to talk to, but a therapist can give us tools. Not every therapist is a good fit so it's a little like dating in finding the right fit.
Be careful about getting stuck in what you're feeling though. Feel it, but then let it go as best you can. Accept that you feel this way but remember it's not forever. Acknowledge it, then let it drift away.
Doing this is the closest I'll ever get to successfully meditating
