I once was lost but now I'm found

"But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy." Thanks Dad for your great mercy. I don't deserve it, yet you have so graciously extended it to me. Thank you Lord. 

I don't want to call someone and let out my stress because I don't even know why I'm stressed out in the first place. All I know is that this entire ordeal about the missing package is giving me a lot of pressure for no apparent reason and I don't want to deal with it. But if I don't, both my parents will be angrier. Why are you so useless? so worthless?  These thoughts run through my head and I feel suffocated by them. Because they're true aren't they?

Feeling suffocated and short of breath. Also stressed out and dreading tomorrow.  Help. 

I get that it's my fault. There's no need to continuously yell at me and point out that I did something wrong. And on a day when I'm already feeling terrible because I'm in pain.
