Ask HN: What do you do if it turns out that your product idea already exists?

There are some improvements I see, but it is very close to what I'd build, and it happened too many times already. I can't execute faster and I don't have enough resources. I got anxiety and depression because of this, but YC says that competitors don't kill startups and there are many startups basically doing the same thing, but they co-exist somehow. So what do I do?
