New medication disaster

So my referral back to the Community Mental Health team has finally been accepted after more knock backs than I can count. After the way things were left at my discharge from Services in December, it was assumed I wouldn't engage with them again. Anyway, that's all by the by now and I saw my psychiatrist and care co-ordinator on Friday. It was an intense hour discussing the last few months with regards to my mental health highs and lows, being detained in hospital again, and piecing together what a period of stability looks like so that I can try with the fertility clinic again. We settled on tapering off Escitalopram in order to start Aripiprazole - and I was really happy with this outcome especially as I've been waiting so long to get back on it after hospital - however, I took it Saturday morning and by Saturday afternoon I'm having a panic attack at work. My nerves were jangling, I didn't know what to do with myself and I felt like somebody was sitting on my chest. I tried to ride it out at work but in the end I went home and eventually had a virtual chat with my local safe haven. By this time, I feel so alien to myself and I'm in tears. It was god awful. What followed was a night of hallucinations and I slept most of Sunday. By yesterday morning, I was almost feeling normal again but it really knocked my confidence at work. My psychiatrist thinks I'm one of the rare ones where the mood stabiliser interacts negatively with the anti depressant. When I started Aripiprazole in hospital, I'd been detoxed of medication for about 3 weeks, so it had nothing to react with. I'm not going to be put off, but it's definitely frightened me with how it quickly changed me in a terrible, uncontrollable way. I want to say it's all the medication, but I have been feeling very low and exhausted since coming back from India and Nepal. The world feels very loud at the moment and I feel really fragile.
