I'm so unhappy

I don't know what's wrong with me. I feel like I'm so unhappy with my life. I've no reason to feel this way. I have a great husband who does his best to help with everything. I just feel like I'm putting a brave face on and scared to actually tell anyone how I'm feeling the now. I feel like I could burst out crying all the time. My 16 year old son is a nightmare and causing so much Hassell the now. is it bad to wish he would just move away.
