So if the person I am jealous of is reading this, then know it's not something you did, it's just something that everyone goes through.

So everyone becomes jealous unless you are filthy rich or you just won't admit it. Jealousy is basically something that I personally can't help. Yea I am jealous of someone but I don't do anything about it and that might be the problem. If you don't talk to anyone about it, or at least tell someone about it, the jealousy can turn into depression. Or something like a show hole, but without the show.
I am definitely not a physiologist or what ever it is, but when our jealous of someone else try to work it out, or tell someone. 😎 (IDK about the emoji)
