Supply issues

I don't know what to do, I'm barely producing enough to keep up with my 3 week old, I pump tons, I tried eating healthier, I got milk tea, I've been eating oatmeal with flax seeds in it. I'm pretty sure I'm drying up. I get about an ounce from one boob and 2 or 3 from the other. a week and a half ago I was getting 8 ounces a pumping session and now I'm lucky if I get 3. I don't have a vehicle to use at the moment so going to see a lactation consultant isn't in the cards. I'm at the end of my rope. I literally have 1 bag of milk left and I just pumped so I won't be getting more for a couple hours. Am I drying up? I don't know what to do 😭
