Heightened emotions - lighter and heavier and what may seem at the same time. This is very common and no, you are not going crazy.
You may also feel on top of the world, light, happier and generally much better, and why not? You are letting go of years of baggage.
You are making changes, and there are parts of you that are apprehensive of these changes, and what to keep things the way they have been, while there are parts of you that have been waiting for changes, what may seem like forever to them.
Think of the group of friends who have different likes and there are suggestions flying around. One will feel great and FINALLY while other suggestions might be more like WTF!!?
Tired, and I mean TIRED. Again, give yourself some slack and space. You have been holding that stuff down, way down for how long, and all of a sudden you are asking your cells and mind to let that Sh*t go!! How do you feel when you have gastro - like blahh!! yes? Same when we do the emotional dump. The body and brain need to recalibrate.
This brings to two points - You may have physical reactions going on.. pain, clean out, acne, a flight fever, flu-like symptoms etc this is because the body WANTS to remove, eliminate, reject all that doesn't serve you anymore. So, it can detox from every possible exit point.
