Rant/thoughts: life right now

Not sure how to say this, but I feel lonely or empty and have been feeling this for a long time now. may be more than a year. Life used to be fun when I was in school or college, can't pinpoint what it was that made it good. but now since I entered corporate world life seems monotonous. I have a stable job, good salary, and a comfortable life, but I still feel empty. There is nothing to be excited about or look forward to anymore. Everyday is the same as yesterday was. same work, same people. It is not like I don't try to have fun, I go out for movies, travel once a month. But all those seem short term solutions for this issue. I thought maybe companionship is what I need. So I tried dating apps. I got good number of matches, but for one reason or another, things never led to meetings these girls in real life. Have you ever experienced this at some point in life? would love to hear what you did to overcome such feelings.
