Hi No One Mourns The Wicked.
I guess you can continue what you are doing; embracing your freedom with sensitivity.
Perhaps you and your mom can view this as growing pains which may, in time, help mitigate the emotional aspect of these changes.
You have to grow socially, but while you are growing “into” your life, which I know you know includes your mom, your mom sees you as growing “away” from her life.
And to a degree, that is true, and necessary, although you both must remain a very important part of each others’ lives, even if time together on the clock together is not what it used to be, for now.
In a few years, when you are settled in, Iy”H, you won’t be out and about as much, and you both can spend more time together.
Hatzlacha to you and your mom!
