Scared to increase sertraline

Tonight was my 13th night on a quarter of a sertraline pill; I was supposed to go up to half a pill (25mg) after 8 days on the quarter but I've been too scared. It took until Wednesday - day 10 - for my anxiety to die down to a somewhat manageable level and i'm scared that increasing it is going to make me anxious & panicky again.

I've been absolutely exhausted since starting them and I'm sleeping between 8 & 11 hours a night, I can't seem to get enough sleep! I'm having really vivid dreams every night too which I haven't done in a long time. I've been having a lot of dizziness too particularly when in the car & it stops at a traffic light or something and a few times I've been dizzy in my sleep and woke up with the room spinning. I can't really see how a quarter of a sertraline pill can be responsible for this but what else could it be? I'm scared that if I increase, all these symptoms will intensify if they are being caused by it. I'm now regretting not just starting the 50mg at the beginning. I'd be on day 13 and the symptoms would be dying down now and I wouldn't have to increase anything... ah well, not much I can do about it now.

p.s. Still haven't taken any more valium but have them on standby for the increase

Hope you're all well!

Tonight was the 7th night of taking a quarter of a sertraline tablet; I have one more quarter left and then it's up to half a tablet - 25mg. I'm anxious about the increase. I've been extremely anxious the last week although I doubt I'm even taking enough of the sertraline for that to be the cause. I've hardly left my bedroom, hardly eating and feeling dizzy and off balance quite a lot. Surprisingly though, my sleeping has been great - I've been sleeping between 8 & 10 hours a night - very unlike me! On Tuesday I had the doctors so I had to leave the house for that. It was horrible. I had a long wait in the waiting room, it was absolutely boiling and I thought I was going to faint. I just wasn't in the right frame of mind for it. The doctor was great with me though and I left with a prescription for diazepam (valium).

I never in a million years thought I would ever touch valium for my anxiety; it was a route I just didn't want to go down but due to the anxiety I've been experiencing this week I had to take it to stop me losing it completely. I only take 2mg but I'm allowed to take 4mg 3 times a day. So I'm not relying on it too heavily and I haven't taken any in the last 2 days. I was terrified of meds like valium and I've surprised myself with taking it. I still have stupid 'what if?...' thoughts when I take it though but it's getting easier and I like the relief it brings. I imagine that I'll need it for every increase of the sertraline though. Even if the meds don't make me anxious - I know that I will - it's nice knowing that I have something that will take it away within 20 minutes.
