Hi. I'm not in dressmaking, but I'm sure if I was, I'd be drowning too. I'd like to take it someday, but I don't have a knack for sewing or anything like that. Sounds like you've transferred into some other class - hope you like it better than dressmaking.
I'm at the end of my class, and just have the final project to do. For some reason, it's kinda overwhelming and scary, even though I think I can do it. Sometimes just doing one or two little things towards the completion of it helps, or even just saying to yourself, "Okay, I'm just gonna do this for five minutes". Then, after 5 minutes, you may want to do another 5, and start making some progress that way.
Hope things are better now. Good luck.
