This is pretty common, I'd say we're all like that to some degree. At least I am - I get a rush every time I like someone and I can sense they like me back and it feels like everything is right with the world. It can be a pretty overpowering feeling but there's nothing wrong with it, unless you start over-analysing things, which I think is what you do. In which case what you need to do is to... stop. Much, much easier said than done but you have to try. Stop checking your phone every two seconds, try to stop bad thoughts and think nice things, go for a walk, distract yourself...
1AM is a pretty terrible time to ponder about your life, so go sleep and never stay up this late to think of how's your life going - 1AM should exclusively be reserved for fun activities or sleep. Philosophising about yourself at this ungodly hour does you no good, you overamplify negative aspects and think not so nice things that aren't true. So if you haven't done so, go get some sleep. A good night's sleep brings a lot of clarity
