I says I have to take it to someone in the middle of the abyss. I have been using the fairy rings ALR to get to non multi combat, but I didnt find anyone in the middle to repair my pouch. Can someone tell me how to get my pouch repaired without me dying? And I don't have 43 prayer. Thanks

Try looking at this guide on the main Tip.it helpsite: The Abyss

 

 

 

In the very center of that map, there is a purple dot with the label, "Dark Mage (npc)." The abyss consists of two sections, the outer section (which contains abyssal creatures [monsters]) and the inner section (which contains the rifts for entering the various altars and the Dark Mage).

 

 

 

You have to get to the inner section of the abyssal space and speak to the Dark Mage. Go through the conversation and he will repair it for you. You usually have to repair your pouch once every 1k runes or so.

any tips to avoid dying?

Not sure what level combat you are? But just wear armour, bring food and maybe even a sara brew (they raise your HP and defence level by 15%). You're really not in the "outer part" for very long. Bring a pick axe and/or a hatchet so you can mine through the rock or cut through the tendrils to get into the inner part.

how do I use a pickaxe to get through?

Just have a pickaxe in your inventory (or wield one) and click on the rock. Then you'll automatically "mine" your way through.
