comedown of venlafaxine(effexor)

I have used venlafaxine for 3 years with sertraline with it for its first year. I thought I already don't feel good because of family issues so I quit it that I think what would be not the worse feeling.

I've quit it because I was an intelligent guy 3 years ago. Now I can't think throughout, I can't focus at all. I don't want to flirt with girls bla bla bla. I'm thankful for this medicine to help me to get out of bed years ago but I feel like it is an addiction lately. Just too afraid to quit, tried quitting multiple times, and after 5 days the withdrawals were too much to handle so I used it again.

Anyway. I'm on cold turkey for 2 weeks but electrical sensation in my brain and my body still remains. I have hatred for everything like everything. Today I cursed my shoes for 1 hour. Yesterday it was my air heater etc. When I turn my head it is like my brain is pivoting my head and it took 2 seconds to go where my head is. nausea, lightheadedness, fatigue, muscle pains are all there.

What the hell is that really? I have quit cocaine more easily than this. I can't even think of my psychology than physical tolls of this withdrawal. When will this end?
