Hey Laura, everything is going to be ok. Just think back to how happy you were earlier, you can be that happy again. Just keep going with that thought in mind, ok? There will be ups and downs, right now might be a down, but that just means that you're getting ready for up.
Just keep writing, getting everything out helps. You really are making so much progress. I'm always here for you
EDIT: Of course I'm not going to knock you over, you are doing so great! You might be having a rough spot at the moment, but overall you are really making so much progress. I don't even know what I could even say to knock you over without just making something up. What you did earlier this morning, that really just shows how hard you are working to get better
