I can't keep pretending I have the energy to complete my GED

I really, really want to enjoy learning. It's always been super important to me. But I've had to start over so many times cuz I'd make progress, something would make it so I can't attend for some amount of time, then I'd forget it all. Atp I'm just unemployed to focus on school. I don't even have an excuse to miss class or not keep up. I mean. It's individual plan. So there's not even any such thing as keeping up. It's at my own pace. But if I stop to "rest", I'll have to start over again. Because no amount of rest is actually healing. So I just try to rush through, get the right answers, forget how it works by the time it shows up again and half ass my way through everything. I don't think any of this will benefit me. I'm just doing it for my parent so they can think I have some hope in life or whatever. I'm just at so many different impasses.
