Just started but ready to quit .... please talk me out of it

[Latimer Luis]

I "kinda, sorta" closed on my first Duplex today. This will be my first multi-family and my third investment overall. I'm still a novice compared to many folks in the community, which is why I'm posting here in "Starting Out."  I feel like I'm learning a LOT, but the process seems to be getting HARDER and not EASIER. 

The reason I described it as a "kinda sorta" closing was because my lender's numbers changed last minute and so I didn't sign the closing disclosure, but I did sign everything else. I'm not sure if this was a mistake to do this but I guess I'll find out tomorrow. There was a closing "team" comprised of the title attorney, a closing coordinator for my realtor, and my loan officer, but many of them were out in the East Coast and I'm on my own here in California. I was told the problem is between me and my lender so I have to "work it out with them". I honestly never felt so alone. For what it's worth, it's also my birthday and I was hoping to give myself a wonderful gift. It could be the reason for why I'm so bummed out about this current "deal." 

Has anyone felt like giving up, but didn't? If so, what kept you going? I just need words of wisdom or encouragement from this fabulous community.
