So I'm afraid of being alone. Not now but in the future. I live with my parents and I'm afraid of being alone after they die. Also I get really bored if I'm alone for a long time. Let's say if I'm alone for more than half of a day I get really bored, dunno what to do with myself and stuff like that.

I assume that you're quite young, and dependent on your parents, so of course the thought of being without them is daunting. But consider that in the future you may be more independent, and you'll certainly have more/closer friends whom you can rely on in the case of your parents passing away.
