How to get out of this

I've been alone for the last 10 years. I struggled at the university due to dislike with dorm life and got more and more introvert. During university and afterwards, I started making money online which was good at certain point. But now looking back, it prevented me from finding a regular job and getting blended in life. Now it is extremely difficult to land a job which I looked for just social interaction and then gave up. Finding a girl as a partner on online apps is very difficult, most are not type of girls I would date / get married. I just want a normal family-oriented girl. Meeting such girls outside or around family circles and developing the relationship is also quite difficult while I feel extremely sad deep inside and can't fake it much. I live alone but sometimes stay with my family. When I'm with my family, I feel better but I feel like my life is not going anywhere. I don't want to age alone and die alone. I'm currently 30. I just want to get married and have a family with a normal girl just like other people. But I feel extremely stuck and sad.
