Sleep messed up again

Its difficult when immense sadness sets in, you are lonely and not near extended family.  I haven't been feeling very well lately so didn't make it to the gym the last three days.  I've been crying a lot lately and wish I could stop it.  I go in and out of pockets of doing school work because I'm forced to -- but this is no way to be learning.  Sometimes I feel theres not much to living anymore and that my life has become an existence.  My children care so much for me and I for them, I hate when they see me this sad.  I hope that things will get better in time.
