Do I need professional help?

Two years ago, I was talking with my closest-and only- friends. Out of nowhere, a major political event occurred over the media, and my friends became visibly upset over it. I disagreed with them, and offered my own perspective on the issue. Heat was exchanged, and I called my best friend a coward. They all turned on me and essentially told me to fuck off. So I did.
I took my political perspective to social media, and everyone disagreed with me. They debated me, and refused to listen to what I was saying. They called me crazy, ignorant, and even evil. I received texts from my ex-best friends about how much they ‘hated my guts’. 
In one day, I lost every single friend and acquaintance I had. They all loathe me, for reasons that are unjustified. 

Every time I see them, 7/10 times I have a panic attack. If not, I become angry, guilty, hopeless and detached. I dream about it almost every night, and when I talk to myself I pretend that I’m talking to them, either to debate or to pretend that the argument never happened, and that we were still good friends.

I cannot handle the fact that these people run the world. These people who lie to their people and manipulate them into believing that they are the ‘good guys’. It DESTROYS me.

I am on the highest possible dosage of my antidepressant. I am desperate.

Please help.
