Depressed

I know this is kinda pointless but I just feel very sad and depressed. I'm 15 and waiting to take my GED, I have 0 friends in my location and I hardly have any interarction with anyone other than my mom, whom I do have a good relationship with, but also my step dad where there is a mutual dislike to put it lightly. My sister moved for college and I still talk to her but it's not the same. I only speak to my biological dad on occasion, due to an event in which he shortened his own life which I think has caused some unknown trauma, even though I still love him and he loves me. I'm pretty sure I have trust issues, I usually never talk about myself in a personal way. I hate myself for being lazy and aimless and whining about everything, I hate that I know almost nothing about myself. I guess I'm just in limbo waiting to go to college and do something with my life, and actually meet people, and have fun, truly enjoyable, simple moments with people, and really just explore the world. I know that everyone has their trauma, and their awful experiences, many worse than mine, but I just needed to talk for a little.
