I've seen some beginning knitters who take on a project that is beyond their abilities. They will start a pattern just because they like it and quickly get into trouble. What I did was to go to sites like Red Heart or Lion for patterns. Their patterns are grouped according to ability: beginner, intermediate, and advanced. Gain some confidence and immediate satisfaction by knitting some great beginner items. Hats and scarves should be easy for you. They do have mitten patterns also. If you don't know how to do something, Google it or Youtube it. You can also ask here.
When you are reading a pattern, you will come across instructions such as *k1, p2* k2. This means that you should repeat all the instructions within the asterisks to the last two stitches and knit the last two stitches. Sometimes these are written as [ ]. Some patterns, especially baby ones, are written in multisizes. It will say increase 0 (1,1). These are for the various sizes, newborn, 6 months, 12 months, etc. It helps to print out your pattern and circle the numbers for the size you need so you won't get confused. I had a hard time with certain patterns only to do them with ease a year later after my skills had improved. Yours will, too. Please don't give up.
Edit: If you're really stuck, you can take knitting lessons from a local yarn shop or just go in and ask the owner for help. Mine is glad to help clarify some part of the pattern for their customers.
