How can I tell people to F off?

It sounds like you are under a lot of stress and need relief. But, be careful about whom you do decide to lash out at. It could get you fired or alienate you from others. If you do not like certain behavior from others, then leave the area or tell someone it is a private matter. Also, get out and exercise some, by taking a walk or something else, you work off your inner aggression.

Sponging off of other people usually comes with some inconvenience and annoyance. You've certainly made more than your fair share of mistakes in life and perhaps that's why your stepfather tries to keep such a handle on you. So maybe go to him and apologize for having been so irresponsible in the past. If you admit your mistakes and promise that you're working on becoming more responsible he'll probably trust you enough to ease up on the rules. As for the food, get a cheap dorm fridge to keep in your room so your siblings won't have access to your groceries.

Try opening your mouth and talking to them. People can't read your mind.

If you want to be left alone then you are going to have to leave. THERE ARE NO OTHER OPTIONS!!!

If you leave your family then you will have more privacy depending on where you choose to move.

I don't know how you got bad credit, but that won't stop you from leaving. You claim you work, and if you have a source of income then you should be fine. If you owe money then you can always pay it back. I don't know if you declared bankruptcy. If you declared bankruptcy then you can still move out. You should make sure that NEVER happens again, and you would have to manage your money a lot better.

If you want you can quit your job since you don't like your coworkers, and bosses behavior. I think there are a lot of other people who you can work, for. If you choose to quit then I suggest you have another job lined up before you quit.

In certain situations, like yours, doing so just isn't in your best interest to do so. You have too much at risk to alienate the same people you depend upon. And if you are more willing to appease them, you usually get along better in the long run.

You are a hard worker but you ultimately live in their house, you know the old saying, their house their rules and BS. You sound stressed like you need a few days away, mini vacation....try to focus on that.

you can always rent from someone if you cant afford your own place

just tune yourself out. u can not make other people do the things YOU want

Extraordinary question! "Family’s BS, petty childish behaviour; demanding and rude; rude stepfather... I hate that my siblings …." Nobody is perfect! Nor is anybody completely bad. Clearly you are working very hard, but a more relaxed and positive approach would probably help things - and improve your relationships. It isn't my place to criticise or judge you of course, but you might find a smile, humour and acceptance will help you to feel a little better. Good Luck!

Sorry but it looks like you don't get along with a lot of people, it's probably not everyone else so you should maybe re-evaluate how you're conducting your daily life.

What exactly does stepdad stop you from doing? What you should be doing is going to work and taking care of your child, life is about your kids not yourself when you have them.
