Depression comes and goes. In your case, the increased thoughts of suicide makes me think that you may be struggling through more than you let on. In any case, it's an alarming symptom and I really encourage you to seek out a therapist of some kind.

A common misconception is that you have to be on the verge of being institutionalized before you should seek a therapist. NO! Therapy can be a great tool for people who are only slightly bothered by depression or are going through some tough external stressors that they need help with. In other words, don't treat it as such a monumental thing. It doesn't need to be. It can be more like visiting the dentist than meeting with a brain surgeon.
