So frustrated.

So I'm rather new to SC and RTS in general but I love watching the pro games and I'm always watching streams and the daily so I decided to try my hand at it. Now its been about 2 weeks and Ive gotten better but I am in no ones eyes anywhere near good. And right now I'm just so very very angry with the game to the point of I dont even want to watch my replays anymore. I have no clue how to deal with anything, like at all, I can scout because I have no clue what to look for, my timings are always WAAAAY off, I never know when to stop droning, and I just have no clue how to go about getting better. And ofc all the while Im being cheesed and dealing with hour long turtles. Can someone please just help me out, I also never know when to expand or what to spend money on.
