I am having anxiety

So this year.. I have been suffering from anxiety. I realize that now. I took a weight loss pill this year that has SSRI like effects. Each time I would take the drug I would feel happy and nothing would really get to me. While on the drug I had fuzzy thinking while off it, I was clear thinking and overwhelmed with anxiety.

I have realized just how much of my weekends have been spent worrying about my cat. I mean I can't go a weekend without thinking there is something wrong with him which always turns out to be nothing. Do you know what that is like? To obsess all weekend that there is something wrong with him and half the week?

Going to work makes me too busy to worry about things.

Then I keep imagining scary things and acting accordingly. In late august I became obsessed with being a prepper. Some of it was due to the north korean thing but once I took the drug again, it all went away. Now of the drug, it is coming back.

I hope this is just a side effect of getting on and off the drug but I don't know how I am going to do it.
