Overthinking. Is it good or is it not?

Just got home and finally I can lay down on my bed, checking the virtual world. It's been a pretty tiring day. Not just physically but also mentally. I think a lot lately, way too many maybe. Eventho I always been an overthinker but now it's just too much that I feel the need to pour it out. I don't know how to start it. It's just too much. It's about my education, future, career, relationship, family, priorities, and the list goes on. So I just got 2 interviews in two days. I think that's made me realize about my responsibility. I finally realize that I now have a responsibility, that I'm responsible to myself, I can't depend to my parents anymore or anyone. And it just feels so heavy. I envy people who can enjoy their life without thinking about risks or the future, because I can't do that. I think to much. Some says it's a good thing tho. But how is it good if it makes me feel worse because I just realize if I'm not good enough, whether I missed some chances, or if I made any mistakes or wrong desicions. I always wondering 'what if' bla bla bla. Ok this post is getting nonsense now. But it is. I see everything is nonsense now, or at least yet. I start to worry about anything. Everything becomes bias now. I can't see the path anymore and I don't want to make any because I'm afraid that I will loose it. Sigh, for now, I'm just gonna let this weigh drownes me into the deepest sleep. Wish me to not thinking too much tommorrow, no?
