I'm concerned.  It looks like you've started down the wrong road. It happens. I almost did the same when my own high school days were about to end. My friends planned to go in a different directions and I didn't know what I wanted to do. And I couldn't stay in the same room with my mother for more than a minute without throwing something and stomping out the front door. It wasn't a fun time for me (or my mom) - but it didn't last long. I got out of her hair by joining the Air Force. Smartest thing I ever did up to then. From 18 to 22 I managed to become an adult.  Now, you won't agree with most of what I say - but I encourage you to at least  give some thought these comments. Now and then you and you mother clash. That's normal. The bitter name calling and crude language and resistance to her attempt to teach you where the limits are and what is expected of an adult - simply haven't worked very well. There are probably a lot of reasons; your dad passing away so early, the expense of bringing up two kids in a single parent family, the increasing pressure of inflation and the cost of living. It's been a hard go for your mom. Think about it. She's had virtually no help as she has tried to be a really good parent. Both you and Ashley have gone thru several frantic rebellions over the years. If they don't get terribly bitter, they usually end on a peaceful note. This period from 18 to 22 is difficult for many because it is the period when a person 'grows up' and becomes independent.  For some understandable reasons you haven't quite made it.  It's important the you change from dependent to a contributor, and the time has arrived. You might, for example, work out a simple budget for yourself.

Rent, Lease, Food,  etc.

School, Tuition, Books etc.

Car, Gas, Oil, Upkeep etc.

Entertainment

You also should (as long as you live with your mother) agree to do several appropriate chores around the house. You should agree to pick up your stuff daily from the common areas of your house. These things are a start on becoming independent. The Army or other military service will teach you the rest.
