Help me please! I'm so upset about my bike ):?

You went for a quick fix and didn't try to find out what was involved before you started. Painting a bike is a multi day project. You start out with completely dismantling your bike down to the frame and fork. You then sand down to smooth everything out. Painting is a multi step process, you have to apply primer first, several coats of colour, then a clear coat. There is no possible way to do this in a day, the paint has to dry between coats. If you want to ride your bike today, put it back together and ride it. If you want it to look good you have to take the time needed to paint it properly.
