Your worth as a person isn’t measured by your ability to find a romantic companion
You are simply a person, people of the alternate gender are simply people. There is no magic transition that happens when you find a relationship, people are depressed in and out of love.
My recommendation is to find community, leave the house, look for public events, join board game nights, pick up a hobby like pottery or biking or a specific video game, get really into something and enjoy your platonic time with people who also enjoy that thing.
Platonic relationships have just as much value as romantic relationships.
I met my SO in an uber randomly, we’ve been dating for 5 years
