Hi Amanda, I am sorry that you are having such a tough time.
It can be so hard to think straight when we’re hammered by insomnia. Still, I see a lot of solid advice in the posts you have received. I know when I am really tired, it can be hard to slow my brain down to where I can actually read and absorb what people are telling me. I hope you can go back and read them again, just taking your time and not putting more pressure on yourself.
I would add one point. If I am reading between the lines correctly, it sounds like you get off a sleep schedule sometimes with partying. Sorry if I am off base here–disregard if I have this wrong. But if you are drinking a fair amount, especially late at night, it is a surefire way to botch up your sleep. I know from experience that while drinking definitely helps in the short run, it gets shorter and shorter.
Finally, you have written more than once that you don’t feel you can take it anymore. I totally get it, and I gave suicide a lot of consideration as a way out. If you are, calling a crisis line is a good plan. Google Crisis Line and it may take a little bit of rerouting, but you will find you are not alone in this. I used to work on one, and I think there is a new access number: 988. In any event, trust me on one point: these are people who want very much to talk with you, and you can be very candid and not worry about whether they can handle it. They can.
Like Scott says, setbacks can be disheartening. Unfortunately they seem to be part of the process. But no matter how bad it has gotten, you are not condemned to poor sleep forever. I know it can feel that way, but feelings are often not a very good barometer of the way things are. Yes, they are strong and so they seem convincing, but again, this can be the insomnia talking, things get so distorted.
I hope you can stick with this forum. Take care.
