Paranoid

I feel very insecure right now. I already have a very good offer, but why do I keep wanting to get other (not so good) offers as well? Why can't I be satisfied with what I have, accept the offer and never think about it again?

Part of me is scared that I will change my mind drastically in 2 months time. The other is me worrying that something goes wrong later and the offer is withdrawn. Paranoid. I expect that soon, I will be having nightmares about these stuffs.

Sleeping at 3am writing essays wasnt how I pictured life after A-levels to be =.=
