First off you need Nexus Mod Manager. Although clunky and slow, it is easily the best way to organize your mods.

Seconly you need a program called Wrye Bash. What this does is check to see if anything will immidiatly crash Skyrim when opening and check for conflicts with mods. It truly is the gods gift to modders for Skyrim.

Now I'm going to skip a few steps with framework because most of that is really easy to figure out and would take up space. So now we have the survival mods

My top pick is http://www.nexusmods.com/skyrim/mods/11163/?
"Frostfall uses a sophisticated system to track your location, weather, time of day, worn clothing, and more, to determine your current condition, in a seamless and immersive way. It also features a large variety of craftable camping equipment, including craftable torches".

Next is Which pretty much makes this all worth while.

"The bleedout health bar no longer matters. When your health reaches 0 you will fall on your knees if you have a follower. Whenever this happens you will receive a random disease unless resisted and the "Bleeding" debuff which stops all regeneration for 3 minutes. While on your knees all enemies will stop attacking you and focus on your follower (just like with protected followers). If your follower survives long enough you will be able to get back into the fight as usual. You can use the waiting functionality to stop your bleeding right away.
If you don't have a follower or he gets knocked out while you are on your knees you will black out and receive the "Critical Injury" debuff which lowers Health, Stamina and Magicka by 50 and lasts 1 hour. If you black out again with this injury you will die. The timer for this isn't affected by waiting or your timescale; due to technical reasons it won't visually tick down but keep displaying 1 hour (or later 15 mins). The only way to cure it quickly is by sleeping. An owned bed completely cures it while simply vacant beds change the effect to "Recovering" which lasts only 15 mins, reduces attributes only by 25 and allows for a chance to survive another black out. "Critical Injury" also naturally turns into "Recovering" after 45 minutes".

This one is what really brings it all together

"The Survival Mode mod endeavors to add an additional layer of realism to your adventures in Skyrim, by rendering your character susceptible to such conditions as dehydration, starvation, sleep deprivation, and addiction".

*One of my top 10 mods to date* Monster Mod - This mod adds hundreds of new creatures to Skyrim along with many new weapons that can be found in the hands of a few creatures, fully integrated into the leveled lists meaning they will spawn throughout the entire game.
