Sorry to hear about your loss (Lexi), I know how you feel and what you are going through right now, we lost our little Long Hair Chihuahua 2 years ago, we got her when she was 6 weeks old and she lived with us 15-1/2 years. Windy Lee slept with us every night all those years, it was really hard to get over her passing.
I know some say they don't want another dog, by we got a new little Long Hair Chihuahua (Carmella), within a few week of our loss, and it was so helpful for both my wife and I, to get over the grieving, Carmella has been a blessing and in a way, almost a reincarnation of Windy Lee.
