I know this question had been made ad infinitum here but most of the links are expired and I'm having a hard time finding good sources online.
I'm thinking about going back to college to study fashion design since that was always my dream and I feel it would do wonders to improve myself as a garment creator. I'm pretty confident in the whole thing except for the most important part: sketching. My background is in sciences and I only had the most basic of art classes back when I was a little kid. I was never
good at drawing.
Are there any good books available online for download? I only have a few months to see what I can do and make up my mind and I'm not finding anything in physical stores (I found one book called "The Fashion Design Course" and it had nothing on sketching).
I already bought a few basics: sketching pencils, India ink pens, an assortment of paper, rulers... I've been watching a few videos on youtube but it's all very confusing due to the variety of techniques. I spent 2 hours today trying to follow a video by a channel called Fashion Teaching and I ended up eating icecream out of a bucket feeling sorry for myself because I couldn't get the torso right. I think I'm even drawing worse than I was before.

Does anyone know of good videos that teach in very simple, very complete ways, for people on the very very beginning? I'm not a fan of the whole "drawing over pictures" process as I'm afraid to gain some bad drawing habits.
Thank you and sorry for the long post.
