why is this happening with me?

1st get alone,i mean REALLY alone,,, not where other can hear you. a Beautiful natural setting es the best. Solitude is key.

2nd try to relax a bit,, when stressed we cannot release. if you do anything like yoga or such that would help. instrumental music whatever it takes to let the stress bleed out of you like water from a jug. as the stress leaves you will feel your pains, that makes us tighten up
we fear this, ,,so you must remember that your pain cannot actually hurt you,, it just feels like it will. you may also have anger in there, it can tighten you up again, so work thru that before.
In some cases, Physical exhaustion will help, if you are fit enough run hard fast and long,, swimming is even better!>
once you are exhausted, it is much harder to resist the emotional release.
I hope you can do some of these things
Stress is a KIller

I'm so sorry for your pain. I do want you to know many experience this. You're not alone. It's called melancholy depression. It's when you've gone through so much, you just can't even cry anymore. I will pray for you, if that's alright. The most important thing to do now, I believe, is not to force your feelings. You'll come out of it when your body is ready. In the meantime, please take good care of yourself. Now is a time when you need to pamper yourself. Try and focus on something you enjoy and do that. I promise it will pass. I've experienced the same. If you need to talk, we're all here to listen. You are loved and welcome here. That's what we're here for, to encourage and uplift each other in all seasons of our lives. Don't hesitate to reach out to any of us you feel could help. We may not have an answer for you, but know we do care. I hope you'll feel better soon.

I cannot cry anymore either, i think that when i finally do, i may drown..i have so much emotion stuffed deep down into the black hole of my heart and the tears arent coming. I know i am dramatic

Try to let go and let it out

Meditate and play strategically.
