Inez, I know it's hard to be tight on money, working under pressure, no time to take a break and rest.. but, competitors shouldn't be the reason that makes you quit. Competitors will be always around. Focus on your products, maybe narrow down the numbers of items or scents you offer, be creative and make something unique. It maybe a simple scent you keep secret how it's made, or a type of jar, it doesn't have to be really complicated. If tarts aren't good sellers, just quit making those, if you have not a quite big business with those simply don't make them. I quitted making votives and tarts, too much work for too small income. It takes nerve, and confidence. I know I make really good candles, I can see it anytime I buy and burn other candles to compare to mine. Also, I make candles for a wedding, the wedding planners fell in love with my candles and said they never seen any candle burning so perfectly, so I will work with them too. I know you work hard and well, so don't give up, maybe get a sort of smartphone so you can keep it in your pocket to check emails often and give a quick answer so your customers know you're there for them.
