Based on your prior posts, you're 18 - right?
At this age you're going through changes that are natural for a teenager. We all go through this at various stages in our preteen and teenage years. This feeling of uncertainty and question, will pass. Like most things along the way of growing, you're getting stronger - per people saying that your velocity has increased.
However, along with an increase in strength (velocity) comes hormone changes and development swings that'll settle down in a few months. Don't be over concerned right now.
I've mentioned the above without considering any recent illness, eyesight issues which can effect balance and coordination, injury recovery, emotional stress, and so forth.
