I had my first meltdown yesterday night. I felt that the first trimester is making me feel so worst.

Same! First trimester feels like having a stomach flu or food poisoning that never recovers and still have to work and worst of all have to hide the symptoms from friends and colleagues and have to suffer alone. Terrible experience! But hang in there! Get a prescription from your doctor if it gets real bad! Diclectin helped with my nausea. Do more of the things or eat things you like occasionally to cheer yourself up! I ate ice cream and chocolate whenever I feel real terrible! As long as in moderation, don't deprive yourself!
