Crosses to bear

I do have issues with bipolar disorder and having OCD has been hard.  I realize that things could be worse, but I wonder if this is what God had in mind.  It sounds so weird but I believe that all of us have crosses to bear.  Some of us have bigger crosses than others and I realize that that is what I have to keep in mind whenever I have a mood swing or an upsetting thought along.  Life is too short to complain about the cross that I bear.  I am just grateful that I can overcome anything.  I should also keep in mind that the cross I bear could be impossible to overcome.  I should also keep in mind that nothing is impossible with God.
