Getting frustrated and sad over nothing 😩

Everything keeps making me super frustrated and sad to the point I feel like crying. Everytime I get frustrated my 2 year old seems to get a worse attitude about everything which makes me even more frustrated. My husband is a firefighter so he's gone for 2 weeks at a time so it's just my son and I.  I have been so tired lately with a lot of pelvic pressure and rib and back pain making it hard for me to even play with my son. Just feel bad for him and wish I would stop getting frustrated! 😭
