I sure hope so. So far, my twenties have been pretty terrible, at least in terms of my mental and physical health.
I don't doubt that, but I will offer - as a possible corrective, a suggestion that you think to add some proportion, some perspective - to all of this.
Yes, you have challenges, but you have also enjoyed considerable advantages.
In fact, not everyone has enjoyed your advantages.
Clearly, you come from a reasonably affluent, loving, stable, and pretty supportive family background - in terms of your personal and professional development.
Moreover, at university - while attending a specialist course - you are studying a subject that you love and, equally clearly, are passionate about and, obviously, have an aptitude for.
These are not minor matters.
