Hi there.My apologies for what you are going through. I know all too well how terrifying anxiety and depression can be, espeically when intertwined.
I realize that what you are feeling might make you feel like you are "going crazy" and make you lack for hope.
I don't have a lot of time right now to respond as in-depth as I would like to, but I did want to point out that this feeling distant from yourself and everything around you is a symptom of anxiety and depression: it is called depersonalization. I have experienced it before, particualrly during painful break-ups, it's like the emotional toll of what you are going through is too great, be it anxiety or depression, and so you kind of "check-out," though not consciously. It doesn't help though, because then you just feel more crazy and much more anxious. My point is though, that you are not alone, and that this is a farily common (though nonetheless terrifying) symptom of anxiety.
I am not sure what provoked this in you. Have you had bouts of anxiety/deoression before? Had you been having doubts about your relationship? Overwhelemed with school? There can be many causes, and what you are sensetive to or triggered by may not seem like a big deal on the surface. I know for me, that when I am in a serious relationship and it goes sour, that is when I start to sufer the most major bouts of anxiety/depression.
My suggestion is to consider what you were going through in the months before this occured, and try to figure out what is bothering you, even if it does not seem like a big deal. Have you been seeing a therapist? You mentioned a school counselor, but you did not like them. It can be hard to find a thearpist you like, but I strongly suggest shopping around until you find one you do like, and go regularly. It can really help you understand why you react the way you do and give you tools to help you cope better. As for the drugs, well, they could be exasperating your anxiety, but it's hard to say. Talk to your Dr. about it, I tend to be quite wary of drugs myself, but then again, your mind is a powerful thing, and ca really make you feel nuts sometimes. So, it;s hard to say if the drugs are making it worse, or if you are just worrying about them a lot.
I suggest reading up on anxiety, sometimes it can get to such extremes that you really can feel like you are going crazy, but you;re not, it's ju8st anxiety. That said, I know it can be EXCRUCIATING and so, so scary. Debilitating even. My advice is to be patient with yourself, try to stay social and do the things yu like so as not to dwell too much, and find a therapist you like and trust who may be able to help you fin out what this anxiety is about.
