Serious Concern about Placements

I'm don't know but I think I'm currently at my lowest point in life.. I feel like everything has fell apart I am not able to do anything. Im about to enter 4th year of my engineering... I've been consistently doing dsa, core subjects making projects and working on other skillls too... But it's just I'm not satisfied with myself I feel like whatever I'm preparing is not giving the desired outcome and I'll not be able to do anything meaningful.. As days are passing by its only making me more anxious. I don't really know what to do with this life. Can somebody tell if this is normal or I'm getting too depressed for nothing??
