Eyes get dry using contact lenses. Is it mental because I'm not used to them?

I rarely use contact lenses, like maybe once a year for a single day. So I'm not used to them at all. I always wear glasses in my everyday life.
Last year's Comic Con in May 2016, I wore contact lenses for a cosplay. I ordered them from an eye doctor who tested my vision. They were for my nearsightedness/myopia. They were completely transparent, not for fake eye colors. And they were supposed to be more comfortable than other contact lens brands.
They were pretty comfortable, although I had a hard time putting them on because I'm not used to them. I was pretty careful putting them on. I wore them before I put on any makeup.
I lasted a few hours at the event until they started to bother me and my vision was getting blurry. I put on eye drops the eye doctor gave me. But it just got worse and my eyes were feeling too dry. I just kept putting on my eye drops with the help of my brothers. I managed until I got home at the end of the day, but my eyes were red and they felt dry and uncomfortable.
Has this happened to you? Are my eyes just too sensitive? Maybe I just need to adapt my eyes to contacts? Maybe I didn't drink enough water and my eyes were too dry (I don't drink a lot of water, another problem of mine, but it hardly ever affects me this much.)? Maybe I did something wrong? Or maybe it's just mental from being conscious of having contact lenses on?

Are there contacts that I can sleep in and go swimming with?

I just started wearing contacts and so far I like them but I was curious if there are contacts that you can swim and sleep in because it's a pain to go swimming and you can't see and it's a pain when you wake up in the morning and you can't see so I was wondering if anyone out there knew of any contact lenses that you can swim and sleep in

How is it possible that my glasses prescription got WEAKER? Will Rx lenses be thinner?

Yesterday I had an eye exam & contact lens fitting. My prescription is:
ODâ€Â" SPH -2.50, CYL 2.00, AXIS 107
OSâ€Â" SPH -4.00, CYL -1.25, AXIS 081

My last exam before this was four years ago. At that time my prescription was:

ODâ€Â" -3.25, CYL -1.75, AXIS 105
OSâ€Â" .4.25, CYL -1.00, AXIS 085

How is that possible that my prescription became less? Is this normal? I'm mid 40s male. Also was wondering if this would make glasses lenses thinner? I've always gotten high index 1.67 and have stuck to smaller frames in order to keep the lenses as thin as possible; would my next lenses be significantly thinner?

Is there anywhere I can sell unused contact lenses?

My eyes are getting worse and I've got some unused lenses that are not strong enough for me now, they cost me a lot of money, what can I do with them? Is there anywhere I can sell them or return them to an optician or optician shop? What do you normally do with unused lenses?
I bought them in boxes of 4 and 6. I used half of the boxes of 4 and 1 of the box of 6. Which means I only have the lenses one by one, not a complete box which I could return to the optician.

They all are Bausch&Lomb:

Optima FW, base curve 8.7:
2 of them are -2.50, 2 of them are - 3.00.

Pure Vision:
5 of them, base curve 8.6, -3.50.

Why do Arabs and Iranians think they're White?

It's pretty obvious they bleach their dark muddy skin, wear light eye lenses and dye their hair light. Just look at that aardvark looking "singer" Nancy Ajram with her plastic surgery, she tried to get her fat Arab nose smaller, basically she tried to look more White lol but the surgery is just a big fat failure. So why do brown Iranians, Arabs and everyone else from that shithole think they're White?

What's going on with my eyes?

So recently, my eyes have just felt… Weird. I feel like I can't focus on something and I constantly feel the need to blink. Occasionally my eyes get blurry and take a few seconds to come back (I wear contact lenses by the way). My first thought was that my prescription was changing, but after going to the eye doctor twice in the last 5 months, I've been told both times my prescription hasn't changed. I tried new contact lenses thinking the brand was the problem but It didn't solve anything. I then tried wearing my glasses for a little bit but my eyes still felt funny.

However, I do have 2 Ideas of what could be causing the problem. My first thought is too much screen time (I.e. Laptop for school work and using my phone). My other thought is that I might not be getting enough sleep. One thing that's also crossed my mind is diabetes because apparently this is a symptom, but I'm hoping it's not that. Does anyone know what could be going on?

Contact lenses, axis, round up or round down?

I have an axis of 010 on my right eye and an axis of 170 on my left one. However the axis's available for some contacts is as follows;

020
070
090
110
160
180

is it ok to have a 020 on my right eye?

And do I have either a 160 or a 180 on my left eye?
Added (1). They work for me. FACT

They are limited axis because the lenses are daily's which are thinner, it has nothing to do with lens quality FACT

You don't need a prescription to order lenses online. FACT.

All I wanted was a simple answer, but then I get some anti-contact lens arrogant optician. Thanks a lot.
