I'm 24 years old and started taking Singulair for allergies. I'm so grateful that I saw this website because I have been going through similar depressive, hopeless, conditions. I became paranoid and really angry with people. I also yesterday got into fits where I would cry and hit things in my room. Usually if I get into a muck I can get myself out, but this time around I've been caught in it with seemingly no escape. It wasn't until yesterday that I even thought about the new medication I've been taking (I've been on it for 2 weeks).
