Started Back on My Medication

A couple months ago I stopped taking my medicine for depression.  I didn't think I needed it.  This past Friday, I had a break down and I acted like someone who I was not.  This scared me!!  Even though I know I already lost my boyfriend I decided to take this for him as well.  I am feeling hopeful this is going to help me get better.  I don't ever want to go to the darkside again.  That is not me.  I hope it's not too late to be a better person.
