Can you recover from a PIP?

I've never had an office job before and I had a review. My boss told me that I needed to improve within a certain time frame or that this job wouldn't work out for me.

I'm doing my best to stay organized and trying to learn as much as I can but I never had any training. There was no handbook or manual, it was more so to find that specific guide that may or may not be in the computer, use the call center, or find an article on the company website.

It's been really hard and even though I'm worlds ahead of my peers, I'm exhausted. I have three different roles and we were going to hire more people but it never happened.

This is my first job out of college and I was so proud. I'm really worried it's not gong to work out and I'm going to be so embarrassed. I always stay late and I SWEAR I try so hard.

Any advice would be appreciated please.
