Looks like depression will be with me my whole life

Everything is going great in my life. Plus I'm actually sticking to my exercise routine! But the past 3 weeks have been a rollercoaster of sadness. It will hit me out of nowhere and before I know it I'm bawling
for no reason! Stepping on the scale at todays doctor appointment wasn't helpful at all, gained 2 pounds. I've been told to see a psychiatrist, but I get the joy of finding one. Don't you usually get referred to someone!?!. Looks like meds are in my near future. I'm a little nervous about the weight issues it may bring up, but at this point I just want to have stable moods.
