Hello, guys. Happy New Year to all of you!

I am in a troubling situation and need some advice. So, I have been prescribed an antidepressant medication. My doctor decided to increase the dosage and wrote a new prescription more than a week ago. My visits to the doctor and medications are covered by the school insurance. The problem is, I'm currently in the process of withdrawing from college and I have also petitioned for the cancellation of tuition and fees for the past semester. If the school approves my petition, I am going to be charged for all my doctor's visits and medications as if I didn't have any school insurance (the amount is a lot). Since I was not going to add another $355 or so for my medication (price without the insurance and generic) to pick it up from my school pharmacy and am currently totally broke at the moment, I went to the community walk-in clinic and got the medication prescribed at the new dosage.

I have picked up the medication at their pharmacy. The problem is: I'm awfully hesitant to ingest it.
Why?
1. The doctor at the walk-in clinic didn't want to write me a prescription because he called a psychiatrist there to get an approval for a medication adjustment, and the psych was hesitant to approve it. After me getting a bit upset at the situation, he eventually agreed. The doctor said that he was going to give me only a 5 day supply until I see a psychiatrist. So I waited quite a long time for him to get the paperwork done or whatever and get the prescription from him. Then the prescription says 30 days supply. What the heck? Also, I showed him a bottle of benzos that I am currently taking, and he was immediately, like: where did you get this from? ....He was alarmed and I found it weird. What the hell?
2. I have had a bad history with this walk-in clinic. They have been so unhelpful in the past encounters with them it's not even funny. They wouldn't prescribe me a benzo, even though I clearly needed it as much as air (ended up with an antihistamine which, of course, didn't do crap). And the psych there called the security on me after I got a bit upset with him. VERBALLY. They proceeded to put me in handcuffs and shipped me off to a psych unit against my will!
3. While I was waiting in the clinic's pharmacy to pick up my medication, their security guy kept entering and leaving, always dropping off a small package (and maybe leaving with one as well, I forgot). I also was not charged for the medication because the pharmacist said that the cashier's office was closed that day. I found these two things weird and unusual.

So these things, all combined, made me alarmed and wary of taking the newly filled medication. Because, what I suspect is that the doctor told the pharmacy to fill me a different medication that would harm me. Maybe that's why he took such a long time to process the paperwork and give me a prescription. In my past dealings with them, I don't remember them taking such a long time and the waiting room was filled with patients! (This day, I was pretty much the last patient left) Maybe it was that security guy who dropped off the harmful medication (who might have cooperated with the local police). I know this sounds totally delusional but what if people in control in this city are conspiring to harm me? I have been having these thoughts consistently for a while, and I have experienced weird things happening to me while in public (people staring at me weirdly, cars leaving in the neighborhood leaving when I walked by etc.). I still cannot make out/up in my mind if I am experiencing paranoia, or people are conspiring against me. Believe me, I have several theories why they could conspire. But that's why I need to take the increased dose of my medication, to get better and solve this problem for once and all (hopefully). Now I am stuck here, still taking a lower dose. I am not going to take a risk of ingesting the pills from a pharmacy of a clinic I don't trust. But that would leave me with a choice of getting it from my school's pharmacy where I would pay, again, about $350 for it. These two options are, of course, immediate choices.

So, what do you recommend, guys? Any thoughts or advice? Do you think I could be suffering from psychosis? Could it be my severe depression and/or severe social anxiety disorder acting out? Does it make sense to feel and think this way? By the way, I live in the U.S.
