Venting out again because Im feeling very down today

Im a very shy and introverted person and working in tech which is infamous for affairs and what not. I don't talk much with people in my office, my day is almost monotonous which consist of work and doomscrolling reddit. I'm 25 and people of my age have lots of friends and have been in many relationships but i never even had opposite gender interaction. I cannot even talk to a receptionist if she is a women. I want to feel loved and affection because I feel to lonely at times, I don't know where to escape from this world. I was not like this till 12th but in college and work i became too isolated and cuttoff from the world, at this moment I have no friends, I work remote mostly and human interaction is almost 0 for me. I cannot go and mix up with people so easily. I tried going for walks felt nice but then when I came back home it felt as if more loneliness struck me. I don't watch any web series lost interest from it as well, bought xbox sometime back and it is lying as it is don't play it. Days go by and I still have the same routine, I was a bright student and now in a good career but still not happy, I m not with anyone, felt dire need to talk with someone. At times it is very daunting to be like that.
