Feeling guilty about moving out

So I'm about to finish my degree and I'm going to be moving out of my mums house soon. I'm going to be moving about 25 miles away so not exactly on the other side of the world. Still for some reason I feel guilty as hell for doing it. She said she'll struggle to pay the rent on her own and will need to downsize. Also it's knowing that she could be on her own every single night from now on.
At the same time I need my independence now. We keep having silly arguments so it'll be good for our relationship.

Is this normal to feel a bit of guilt like this?

Thanks

Yes, it's normal.
Change is a part of life as people age, move on and their situation alters in terms of studying/employment/relationships.
But it can be emotional and unsettling at times.

You mother seems very keen to prevent you from moving out of her home.
Does she have any health issues or financial problems?

Of course, you'll have a feeling of uncertainty. You've (presumably) grown up in this home, it's your safe haven and it's natural to feel the way you're feeling.

However your mother sounds a little emotionally controlling and even, a little emotionally abusive? It is just you two at home?
I understand the loneliness that your mother may feel after you leave especially if she's alone but this shouldn't hold you back. A lot of parents have the empty nest syndrome after their children leave and if your mother is alone then this may be more pronounced.

Your mother left her family and her parents, it's just a normal part of growing up and finding your feet.

Reassure your mother that you can see each other often, it's only 25 miles. Show her the benefits of downsizing (saving money, less cleaning etc).

Be kind but be firm.

Hmm emotionally abusive seems extreme. My brother does come every now and then. But yeah it's mostly just me and her. The thing is before the lockdown I'd often be out of the house from like 7am until late at night most times.
