<human>: Could you distill the essence of the text into 1-3 sentences?

In May of 2009, one of my close friends, at age 16, fell off of his moped and got run over by a car, dying ten days later in the hospital. Less than four months later, my half-brother (by far the closest person in my life) died at 17 from, what his mother tells me, a conflict in his medications causing his blood toxicity level to be too high. When she called me to tell me he passed I was on my way to pick him up to go to Silversun Pickups, his favorite band. 

For the first year after that, granted I took one semester off of school, but I functioned really well. I would have small break downs but then I would be fine. Now, almost two years since Evan died and a year and a half since my brother passed, it's starting to take a toll on me emotionally. But I feel like it's too late to "seek help" or talk to people about it because I feel like I already had that chance, and now I would just be a bother.

Do I just wait it out? Or do I have to pay a stranger to listen? Should I have been over it by now? I don't know how this whole thing is supposed to work because I don't know any body else personally that has lost both their sibling and a friend in high school, and everyone that knew them back home definitely doesn't think about it anymore.
<bot>: My friend died in 09, my brother four months after that, and it's only just now hitting me. When does it pass? Why am I reacting so late? Ugh.
