Am I overthinking or how to navigate further?

Today, my mom said "That's why you have no friends". She told me this infront of our family members and laughed about it. Growing up, I wasn't allowed to hangout with friends and was told by her that she's my only bestfriend and others will just use me so I must not betray her.

I do have friends in college but whenever I get focused in my life, she feels ignored and I don't have a dad so I give her more attention. I share my everything with her and I sometimes feel like her puppet.

She's a working woman and have her own friends. She gets annoyed when I am in call with others, so I give her all my time as much as I can.

Today, she said this and I feel helpless as I somehow turned into an avoidant. I suddenly been feeling so bad as if she wasn't the one who kept me away. I am in another city, studying. I rejected many good opportunities like NITs, just because of her separation anxiety.

how to take my life back? I am so lost, I have severe social anxiety nowadays due to so much restriction since childhood.
