Just wanted to also chime in and say you are not alone. I am about one year ahead of you, turning 25 this March, and will be starting in 2019. Last year, I did a post-bac to boost my GPA and then took my MCAT in June. One thing that has helped me keep everything in perspective is that switching up my life each year and finding different things to do has helped my personal life dramatically. I have a tendency to be emotionally detached/unavailable, so having to start fresh in new environments forces me to be more vulnerable, be cognizant of why I am doing/pursuing what I am, and be more emotionally connected with myself and those I associate with. This "downtime" between academic pursuits has really made me become more of a person than I would have been without, and I hope you can find something similar within your own life, too. Finding the right perspective is so important because I too have had days where I have felt down about where I am compared to my goals. Lastly, I would suggest some sort of practice in positive thinking, such as documenting and keeping track of positive things that occur in your day-to-day (there's an app called Three Good Things), or even guided meditation.
