"No office email address to send concerns"

There's been a misunderstanding and it's set me back. I thought the new nurse person would be seeing me just to see how I was doing on the meds and then I'd be able to try the EDMR therapy. 

I've tried saying how tired they make me but I don't feel they understand how much this is impacting my life. They said to try alarms but I'm so exhausted that I can't enjoy anything. When I needed to cancel an appointment because of my partner's serious health situation (ended up needing surgery), they said they wouldn't be able to keep the referral open and would look at discharging me which made me panic that I was being dropped.

I've tried contacting the previous person I was seeing to ask if there's a general email I can use as I don't feel comfortable talking with this nurse (they are nice but I'm just having trouble), I was given this nurse's email address. I tried again to say that it's the nurse I don't feel I can talk to but I've not heard anything back.

I just need a medication review with the previous nurse who I could talk openly with, and then to see if I can still access the different therapy as CBT wasn't working for me.

I've gone to the doctors to ask for help and they've agreed that the exhaustion is most likely the meds (but are going to do tests just in case it's something else). I'm due an appointment with this new nurse this week but have cancelled it as I'm stressing so much about it. The whole worry over being discharged while the meds aren't working right for me, not getting further therapy, and feeling like there's no one who can hear what I'm saying has made me spiral and self harm again.

I know they're all incredibly busy and demand is high and I feel like a nuisance for asking for help. I don't know what to do. All I can think of is come off the meds and resign myself to being like I was before.
