not doing well again

Was doing ok yesterday and most of today, but then anxiety set in at dinner time. Started having obsessive thoughts right in the middle of family dinner. I don't understand how it seems like nothing has triggered it I was feeling fine. Feel like crap now. I thought about driving off a cliff on the way home but there are no cliffs. I hate this. I'm balling right now. I think I'm going to call the psychiatrist to see about getting on an anti-depressent. We both didn't think that I needed it when I saw her last (about two weeks ago) and now I'm thinking I do need it. I'm at my wit's end. No one deserves to feel this way.
