I don't know how I feel about life right now

For the first time I have hope for the future. I have a girlfriend that I love and I'm on track to get the job I've always wanted. I feel like the bases are loaded and I just have to keep going to have all the things I've ever wanted from life. It just isn't a happy kind of hope if that makes sense. I'm stressed out and anxious about losing what I have. I'm 24 now and I've changed so much so rapidly in the last 5 years. I feel like I've lost so much about myself in my deliberate pursuit of being "normal and happy." I don't play videogames like I used to, and when I do, I don't know if I'm really enjoying it. I don't read anymore, and I don't watch anime. I don't know if I've just changed for the better or just running from my authentic self. I love so much about my life right now, I just don't know if I'm becoming the person I'm really supposed to be.
