You are feeling alone now as you imagine you will feel alone when you move away from your support. Can you arrange for similar support to have ready for you when you move? You put this in place for you where you are, could you do it for where you will be also?

There is support out there. You don't have to be alone.

Moving out, moving on in life, are both stressful things to have going on. Adjustment is very hard for some. I hope you will begin now to find a therapist who can help you with this.
