Every hero origin story has a low point. You might just be in the part they show in flashback.

Every account of someone becoming capable includes a stretch where nothing worked, though that part usually gets compressed into a few minutes and remembered as background. Living through it takes considerably longer than watching it. A low point is not evidence that the story goes nowhere, it is the section that explains everything afterward. From inside, you cannot tell which part you are in.

Rather than judging the whole thing from here, note what this period is teaching you specifically. Keep moving at whatever pace is available. The value of a stretch like this usually only shows up from further along.
