I'm almost 22 weeks and my belly is huge. I'm exhausted from starting school. I'm a teacher and I am constantly on my feet all day. I work between two campuses and I teach three different kinds of classes. I. Am. Tired. My feet are so swollen. My legs are so tired. I have a five year old, a home to clean and take care of and try to still be an attentive wife to my husband. As of today I just want to quit. I keep questioning if I can do this another 18 weeks. I start coaching in October which means I will be putting in a lot of 10-12hr days. I know other women have tough circumstances but I can only speak for myself and say I just don't know how I'm going to make it without being worn down to my core. Please send good vibes and prayers my way!
