question for adults:Do you think my sister's wedding is going to ruin my life?

To answer your 3 questions:

Your sister's wedding is going to ruin your life ONLY if you let it. If you decide to not let it, it wont.

You wrote that you are not invited to the wedding. So no, in that case, you should not go.

If you can afford to leave home, do so since you obviously are not happy there.

If you are being made to feel so awful, it is time to find a way out - whether or not your sister is getting married.

Look for an opportunity that includes board, like cooking for an elderly couple, or as a companion. You may find that through a nursing agency or senior center. If you are a decent person and capable of doing some simple things, there should be a place for you somewhere.

There is no call for the treatment you describe, and no reason you shouldn't have a lovely wedding someday. It may not be the pageant your parents are putting on for your sister, - but then again, will that really be what you want if they are there to abuse you?

Stop allowing yourself to be a victim, and go make your own life. There is a world full of people who can be your family, who will make you feel better about yourself than this. Part of the problem right now is that you haven't become independent, and that is your responsibility. Time to leave - you may feel better about the whole thing from the other side of the walk.

I have been told by my own therapist that the great thing about this world is being able to make your own family. Meaning though you might have a biological family you can form your own from friends who are dear to you.

Mine is not that bad, but they have been a headache. They are very dependent people and were so since I could read and write English. I moved 1,500 miles away, things are better. But they will never be perfect. I feel better and that's what's important. I will never and can never make them happy, because they are not accepting people. They may not accept that, but I do. I am happy living far away.

It was scary. I was lucky and stayed with family who got me a great paying job straight out of high school. I had a family friend who connected me to building management that I started at 19 (8 months after graduating high school.) That is the only way I am able to support myself, two jobs.

I don't think it would ruin your life. I think that you should go to the wedding but if they do anything that bothers you to the extent tht you can't take it anymore, just leave. I don't know exactly what's happened, since you wouldn't really want to share your whole personal, but before you chose which path to go down, ask yourself if what your choosing will make you happy.

If you're not invited to the wedding, then don't attend the wedding.

Get a job, move out, and don't talk to them anymore.

If you dont' want a relationship with your sister, then don't go.
