If you're feeling down or depressed - there is nothing wrong with seeking professional help.
Too many people dismiss these kind of feelings as "all in your head", but the reality is that there are often scientific and medical reasons for why you are feeling this way, and a medical or scientific treatment is 100% the most appropriate solution.
It's also worth noting that the desire to "flee" (and suicide is a type of fleeing) comes from your body telling you that it can't handle staying in this situation much longer. It is a warning sign that you should not ignore, so please seek help.
