h and m grey hoodie burned $2500 on teespring without any sucess! broke ...

Yes its true.Until today, I spent $2500 on the teespring ad on Facebook.Now I have been using teespring for about 3 weeks.Tried almost 15 different designs.Only one of them sold 4 out of 50 and I spent about $60 on that campaign.Its hockey team hoodie.The hoodie looks exactly like the one that sold more than 200 hoodie before.Now, I'm the only one selling more than 200 shirts, but I only sold 4 and have 5 days to get this done.I can tell you about the Anaheim Ducks I'm in.This is my goal.A man/woman who lives in Anaheim, California, over 16 years old, likes Anaheim Ducks, which may be ducks.and so on.I only use newsfeed ads.I did use a custom audience but they didn't give any success.I did these 4 sales when I used the standard target.The center is in the month.5 and 3%.I use oCMP, (click between 0.80-$0.50).Tried CPC, but the ads don't show much when I have a smaller bid (0.30) Oh guys, I share a lot of information about my niche and which team.I do this because I am in a crisis right now.I thought teespring would be a way out, but after spending $2500 I felt like a jerk who threw away the money.When you see someone else making at least $400 in a profit campaign and I make zero on my own, it's terrible.I don't know what to do now.Should I stop and save the 10 k I have or should I keep saving.Bankrupt or not?!.Just as you see people in desperate situations now.: Confusion: Any ideas or help would be greatly appreciated!!
