Taco Jones,
First, unless you are physically active, it seems your daily calorie intake might be too much for you to see the results you were hoping to obtain from these exercises. Barring a physically active lifestyle, you might want to reduce the range to 1900 - 2300.
Second, what do you mean by workout every two to five days? Does it mean you work out every two or five days? If you're working out every five days, you shouldn't expect any result because with the calories you are consuming, you aren't burning calories fast enough for those results. You need to increase the frequency.
Third, don't go too heavy. Every exercise has a good way of performing it and you should only use a heavy weight that allows you to perform it well. If you cannot perform it well, it's too heavy for you. Reduce the weight and try again. This will also help your muscles recover faster.
Since your goal is to build strength, I wouldn't recommend you exercising with light weights. You can start with light weights, but you need to increase them constantly. You also need to perform these exercises every other day; this allows your body to obtain just the needed rest without losing the strength obtained in the previous workouts.
If your body is still constantly sore after a few weeks of exercising, you'll need to add cardio and calisthenics to your routine. These can be done everyday (recommended) or on non-weightlifting days. Calisthenics exercises allow you to use your body weight <em?(which will make you stronger as you progress) and cardio helps your heart and lungs (as well as provides endurance).
You might also need to obtain a personal trainer, join a gym, or join fitness communities online or in person; sometimes, we need external help to blast through the barriers.
One thing you cannot afford to do is doing nothing.
