There are two or three things you can do, and combining them is probably the best way.

First don’t be afraid to use your camera, provided you don’t physically abuse it you aren’t going to break it!

Buy a couple of books. There is usually a “Magic Lantern” guide to most cameras, though the quality does vary a little. There are also a number of books on general Digital Photography, you’ll find a good selection on Amazon, look to see how other users have rated them. It’s much easier to digest this info from books than from websites.

Take a beginners course in photography.

Regards the specific blurriness/softness: Make sure any anti-shake mechanism on the lens is turned on. Make sure you hold the camera firmly, and try to steady your body, knees slightly bent, feet apart and in a wide V. If you can steady yourself against a solid object (wall, tree, lamp post etc). If your images are blurred, use a faster shutter speed. If your images are soft (the Depth of Field is too shallow) then use a smaller aperture. This all assumes the ISO is set to Auto. Blur and softness are in photo terms different, in time you’ll get used to the jargon – it’s one of those cases where the jargon is necessary to explain the subtleties.
