What advice would you give someone whose desire to seek companionship is starting to become a detriment?

You're in college and already feeling this way? shoot, I didn't start having those jealous/envious feelings until my mid 30s. cuz that's when EVERYBODY I hang out with has a significant other or kids or family of some sort. and 99% of their social life includes other couples. which leaves me in the dust. but since you're in college, find some activities or join a club or parties to meet some people.
