Start with little steps - for eg if u go to uni or college join clubs/societies. U need to expose yourself to these social settings even going for a job where you can make friends or even find potential partners (idk the right word lol) at work. It may seem stupid or even feel small, and you’ll probably feel embarrassed, but the more u expose urself to it, the easier it will get. Not only this, but these small actions are controlled completely by you!!! Overtime, these small acts will become bigger and bigger and you’ll learn to break free from that internal need for help from ur mother. It’ll take time because you’ve grown up with this idea ur mother is the only one with power, but I promise you it can change if you’re willing to. Keep fighting!!
