My kitty kept me awake the whole night

So a few days ago I adopted a Russian Blue kitty, 3 months old, the first couple days he was shy and was hiding. But yesterday we have finally bonded, and he stopped hiding. I live in a studio, so I can't keep him in another room during the night. He was crazy during the night, my books fell of the shelve, he dropped my iphone 6 and cracked it, my all make up is on the floor and so on. Also, I only slept 3 hrs and I have a midterm exam today. I don't know what to do, any suggestions? I wanna keep this cat, but I'm even thinking about giving him up… I need to sleep.

I have iPhone 4. I'm suffering from terrible Wi-Fi problem?

Problem is that whenever I'm near to router or wherever signal reception is excellent, Wi-Fi constantly disconnects and sometimes my phone don't search that network. This is not the issue with my router, I have tried it with different routers and internet connections, with different settings but no luck. I have reset network settings, I have installed new firmware but no luck. However my Wi-Fi works perfect is I see two signals on my connection. Like far from router.

I'm under very severe depression?

Because I never had a girlfriend in my whole life and I'm already 19yrs old, I have never been kissed by any girl, never been hugged, never dated anyone either… The last time I had my meal was 2 days ago, I was 135 lbs last month, now I'm only 98 lbs, I only eat once every three days… I'm in the hospital now with my Iphone.

I'm not ugly because girls and a lot of gays used to have a crush on me before, but when I ask girls out I like they just reject me… The biggest part is that, no girl has even kissed me yet and nearly all guys at my age have had make-out…

Any advise?
