I have only once had thoughts of suicide. That was during the prime of my high school life and I was getting shit from a lot of people(family included). What's surprising is that since my room is practically a museum of bladed weapons and other killing objects, the thought to use them on myself only occurred that one time.
I quickly got over it though because "Why should I have to leave my life because of other people, they should go die instead" is what popped up in my head. Of course other reasons came about as I continued living but that one thought really started it all.
Basically if I was to take anything out of that is that you find reasons to live as you keep living.
On to the question of:

Am I a bad and selfish person for thinking about it?
I wouldn't think so. It would probably surprise you(myself as well) how many people actually have considered suicide at least once in their life. I've known many people who have considered(and a few who have actually committed) suicide and I wouldn't have consider them bad people or even selfish for considering or committing. Still, I don't think suicide is necessarily the right thing to do. It is an option but I consider it as the last resort.
TL;DR, I do not believe suicide would be the appropriate solution to your predicament nor would I think any less of you for thinking that it was.
