Need help with my build, Please! Cobra Lash Assassin

Cobra Lash Assassin Glass Cannon atm...
my PoB: https://pastebin.com/fcMwKHH6

If anyone can take just a few moments to look at my skill tree and offer me any help, I would really appreciate it!

While I was leveling this Cobra Lash Assassin I went full on Glass Cannon and focused on DPS. Now that I've hit 79 almost 80 and gotten into maps I'm having a hard time with survivabilty.

I'm rocking 2.5k life lol and anything above white maps is just eating me for lunch of course...

I have a full respec available so now is the time to fix my leveling mistakes but every time I try, I get sucked into all the DPS nodes. I haven't gotten above 3.3k life. I haven't upgraded my leveling gear yet because I don't have the currency at the moment. But I feel like if I could redo my tree so I can do higher maps, the money will come and then I can upgrade my gear...

Any who... Any help anyone can offer me for my tree or my skill choices, any help on anything really, would be greatly appreciated!!
