I'm sorry you had this experience, but I will put the blame on your company's onboarding.
This was your first job so you may lack data points, but if you ended up not getting helped/being supported as a new, out of school, engineer in a remote setting, I strongly doubt that it would have been any better in an office.
I've been a manager/director working with distributed teams for the past 6 or 7 years, I've onboarding dozens of folks for whom it was their first or second job and they all had a really good experience.
