Should I try to find a girlfriend, or should I just learn how to deal with this loneliness by myself?

Problem/Goal:

I’ve been feeling lonely lately, and I’m wondering if I should start looking for a girlfriend.

Context: I 20(M) and ever since I was 17, my main goal was to make a lot of money. I grew up poor, so I decided early that I wanted to focus on building my wealth. Because of that, I never really cared about getting into a relationship. I actually enjoyed being alone, and I never felt lonely before.

Now I’m 20. I spent the last three years focusing on building my business, and it worked out. I’m now earning six figures a month even though I’m still in college.

Most of the time I’m just inside my house working. I only really go out when it’s necessary. Maybe that’s part of the reason.

The weird thing is, these past few days I’ve been feeling lonely, which is new for me. I’ve always liked being alone, so I don’t really understand why I’m feeling this way now.
