a few tips for you:

• try open source software in windows too, like libreoffice, inkscape, etc, depending on your needs. It will help the transition to be easier
• if you have a spare machine, try linux on that instead of dual booting, because windows tend to mess with the bootloader in dual boot
• don't be harsh on yourself. It's normal to have difficulty to adapt to things. You can do that in steps as small as you feel comfortable with
• try distros like linux mint, because they tend to be easier for new users
• experiment wine or winboat for software you need from windows, if there aren't alternatives
