Hi Dianna,
Thank you for giving us that base information. We understand how scary diabetes is and the reality is that we can help you get past the fear and learn how to administer insulin, home test and do it all economically.
You are already doing the first thing correctly which is feeding a low carb food - the fancy feast classics is just fine to use, even the wellness is good (if Espresso will eat it).
So, the next two things we need to start is home testing and insulin.
At first home testing can be scary, but it really isn't hard to do and if you make it fun for Espresso, such as give him special treats only when you test - you may find that he actually looks forward to testing. Some cats go running to their testing spot just to get their treats. Maui used to refuse to leave her test spot until I brushed her (that was her treat, brushing).
Treats can be food or brushing or anything that your cat loves and finds special.

to home test you need supplies. You can do this economically by going to Walmart and buying the Relion brand meter, matching strips and lancets. You don't need to buy an animal specific meter. A human meter will work just fine.
So here is what you need to buy:
Relion meter - most people like Confirm
Matching test strips
lancets - which look like push pins, and are inexpensive - you can get ones that go with the device included with the meter or you can get others and free hand the poking. It is up to you what you prefer. purchase lancets that are 28 or 29 gauge.
neosporin with pain relief - you can get generic brand

Next is insulin. There are three types of insulin that are good for cats - Lantus, Levimer and Prozinc
May I suggest that for economical reasons you choose Lantus or Levimer - as you can purchase single pens with coupons for $25 - this will save you a lot of money for the cost of the insulin. These two insulins work in similar fashion and yes there is a learning curve, but don't worry, we will help you with that.
Most states require a prescription for insulin and syringes, so you will need to get a prescription from the vet - for insulin and syringes.
Ask the vet to write a prescription for Lantus solostar pens and a second prescription for U100 insulin syringes, 0.3 cc, 5/16 needle length with 1/2 unit markings.
When you go to Walmart for the meter, you can buy insulin syringes there - a box of 100 syringes is $13.

We have loads more information to share, but for now, this is good enough to help you get started and learn to overcome the fear.
