Feeling all over the place

So I decided to take a mini vacation by myself to Pigeon Forge Tennessee and I just needed to figure some things out and I'm looking at moving down here so I'm meeting with the realtor but I've never felt more alone and I'm just watching all these families with their kids and I'm beyond saddened because all I want is to not be alone and to have a child and raise them and teach them. So my AF is due June 1st or 2nd and I've gotten negative test still. Pretty depressed right now
