I’m going to assume you are an adult, over 21.
What do you do? Do you work? Are you in school?
Are you involved at your parish and in the surrounding Catholic Community?
What are your interests/hobbies?
Getting out of the house, meet real people who share your interest, your studies, your Faith. Make friends. Join a book club or a dinner club. Friends. That is where you begin.
Then, at some point, one of your friends will start thinking that they want to introduce you to someone, you meet them and maybe you go on a date.
It all begins with getting out of your own head and into the world.
You can be a victim of your disability or you can be a person who happens to have a disability. Your choice.
One other thing. With my disability, it can be random or inherited. When it occurs randomly, parents react in one of two ways. They either shelter/coddle their child, treating them as a “cripple” who is made of spun glass and the child grows up to be an insufferable narcissist or a perpetual victim.
Other parents get involved with local and state chapters of support groups, introduce their kids to people who have the same disability and thrive in the world as well adjusted people who do not let their disability define them. That takes pushing the kids to try things, to risk failure and rejection to learn that they can get back up again.
I hope your parents were of the second group. If not, it is not too late to begin. Find the local support groups, meet other people who can mentor you.
