Sometimes drugs don't agree with you. Don't know because you don't say just how bad your life is, as to whether taking drugs is even necessary at this point, but assuming it is, they all have their bad points. It does take 4-6 weeks for most people to notice the effects they're looking for but side effects start right away. Nobody can predict whether this will last or not, as these drugs affect different people differently. Sometimes, a particular antidepressant can be so sedating you sleep all the time. For others, they can be so stimulating they're anxious and have a hard time relaxing. This is how different the same drug can be for different people.
