I have a feeling you're overwhelmed because you didn't do the proper work up front to ensure scope creep wouldn't happen, and that you'd always feel compensated for your work. A lot of freelancers publish guides for this type of work, and I think you should read one. Also make sure the contract/tax stuff is handled properly too! So you're not stressing next April.

Try reading this guys book, seems legit, maybe he offers strategies for handling scope creep and such: http://texmexconsulting.com/

Then drink a beer, do some Yoga, and relax before the evenings work!
