A typical example of anxiety patient features can be like this –

I’m eighteen and getting ready to go to college in just a few weeks, and I’m going through what seems to be an immense mental breakdown that has progressed rapidly over the past few months. I feel like I can’t think clearly, and I feel like I’ve lost any sense of intelligence I used to have.

I’ve lost the ability to talk or have normal conversations with anyone, even my closest friends and family, simply because I feel like my brain isn’t coming up with what to say. Instead I just feel blank and brain dead. I feel like I have no knowledge inside my head to grasp at.

My parents are well aware of this problem by now seeing as the only thing I can manage to express is that this problem exists.

I was put on prozac today but it will take weeks to actually have an effect, if any. I’m really not sure if prozac will actually be able to help me with this situation. I’m seeing a counselor, and I’ve been told what I’m going through is just a huge spell of anxiety and that it will pass when the anxiety does, but I don’t feel like that’s true.

I just need to know if anyone has ever experienced something similar to this or have any ideas on how I could possibly get over this and live my life like a normal person. Will the prozac be able to help? Thanks for reading this, I know it was just a lot of rambling, I’m just so hopeless and lost right now.
