It sounds like you need to be on a cycle that emphasizes developing the technique and making sure you're in the correct positions. You said you just started in January, was there any introductory phase or a period where you did different drills to break down the movements?
I would suggest the Classic Lift Position/Technique Cycle (book) or even the Technique Development Cycle (book) but that's all going to depend on where you're at because I haven't seen your lifts.
Keep in mind that it takes some time to get the hang of these movements so it's going to take a lot of patience. One year is still considered a beginner let alone four months.
