Confession - just want to cry

So I have been living with my boyfriend for 2 years. Sometimes I just want to cry about life / work / friends / all of it. And just let all my emotions out. Except the problem is, when I cry, my face gets so swollen for about 24 hours. Sometimes I wish I could get a day alone just to cry and not be bothered. Yeah I know it sounds weird. I just need it :( what do you guys do when you just want to cry and be left alone ?
