My Mom Against My Dad Family and Me

I'm sorry to hear that.
Right now, if it was fairly recent, is probably a hard time for families if they are grieving. I'm sure you are going through a rough time.
Your mom might be trying to do what is best for you and giving everyone a little bit of space. She has your best interests at heart.
If you need to speak to someone - a school guidance counsellor, a trusted adult, an aunt or uncle, a grandparent, or a pastor etc. may be a good resource to run your thoughts past. They can always reach out to your mom.
Sometimes there is more going on that we know and I am guessing that is what your mom is thinking of and perhaps trying to navigate. Talk to your mom. We do not know the circumstances. Best to you.

Welcome to mamapedia! I'm sorry your dad died. May his memory be eternal.

How old are you?
How far do you live from your step-mom and siblings?
WHY won't your mom let you see them?

We don't have enough information here to help you. If you are 18 or older, you're a legal adult. If you're living with your mom, you need to follow her rules. However, you need to ask her WHY she won't allow you to see them. Are they drug addicts? Are they in trouble with the law? WHY?

Truly sorry for your loss.

If you are praying, go to your church and talk with your priest, pastor or rabbi.

You really haven't given enough information as to why your mom is not allowing this. How old are you?

Did your mom and dad share custody of you? Were you with your dad when he died?
I have more questions than answers.

Go to your school counselor. Ask him or her for advice.

Hi G.,
I'm going to suggest several people who might help you. One is your school social worker. The other one might be your pastor, as you mentioned you've been praying? Other folks might be a trusted teacher (past or present), school nurse or counselor, or your principal or vice-principal. Please let Mamapedia know how you do so others can benefit from your actions! Kindest regards to you. And take pride in your strength and love.

Sorry for your loss.
You might have to wait until you are older to see your extended family again.
With your dad gone your mom may not feel a connection to his ex and other kids.
While it might be nice if she acknowledged your half siblings - she didn't marry this other woman and have kids with her.
Maybe in time after she has had a chance to come to grips with her grief she might feel differently.
In the mean time - she gets to decide who to interact with and who her family is.
You are grieving too but cut everyone some slack and talk to your guidance counselor at school about it.
