18 days in of Venlafaxin - help!

I'm now on 150mg per day and I take it before bedtime.

When did you begin taking 150mg? If recently this probably accounts for the increased anxiety/panic.

Started yesterday, increased anxiety came 3 days before- out of the blue sadly

Then the increase was most likely because the med hasn't kicked-in yet. It is still early days

So, now on day 47, 11 of those on the double dose of 150mg. No improvement in fact last week my anxiety was increasing and because I have been taking Lorazepam for about 8 weeks now, the doctor added 50mg pregablin to the mix, to reduce the anxiety.
Since last Thursday, I’ve been steadily feeling worse, very tearful at times, very low mood and high anxiety. Today, the doctor said to stop the pregablin in case it was interacting in some way.
Could the pregablin cause this or are other factors contributing?
This suffering is all rather relentless, but I’m still confident that the Venlafaxin will work in the end. But please can it work soon as losing hope slowly

Upping an AD dose will often increase anxiety levels for a while. Doubling the dose in one hit isn't ideal.

and because I have been taking Lorazepam for about 8 weeks now, the doctor added 50mg pregablin to the mix, to reduce the anxiety.

So you're taking both lorazepam and pregabalin? I don't see the point, but if it works then okay. The one advantage of pregabalin is it doesn't have the same negative impact on hippocampal neurogenesis as the BZDs. It may even speed up cell maturation a little.

Today, the doctor said to stop the pregablin in case it was interacting in some way.

I think it is more likely to be due to the venlafaxine dose increase, imo. You will soon know whether pregabalin is the culprit because it has a short half-life, around 6 hours, so it should be completely out of your system within 30 hours. If nothing changes within 2-3 days then it probably wasn't the problem.

This suffering is all rather relentless, but I'm still confident that the Venlafaxin will work in the end. But please can it work soon as losing hope slowly

Unfortunately, there is no way of speeding it up and as you've been on ADs before it is likely to take a little longer for the venlafaxine to kick-in.

Update
Day 54 since starting on 75mg, day 17 on double dose 150mg of Venlafaxin.
A week since my last post and a lot has happened and I’ll try and explain.
My symptoms got worse culminating in an awful experience on Friday afternoon (it’s Sunday today).
My doctor, last Monday, had restricted me to half a Lorazepam tablet per day, but I was having to take one tablet basically to have any effect.
On Friday I was desperately trying not to take a tablet but I did eventually give in as I was having a severe panic/anxiety nowhere is safe attack. Truly horrible.
The doctor prescribed me diazepam, 4mg am and 4mg pm instead of the lorazepam. I have taken it yesterday and today as prescribed and not touched the lorazepam. I’ve had some very anxious moments in the last 2 days but managed to stick to the plan.
I had been taking the lorazepam for around 8 weeks, as and when needed, and averaging somewhere between half and one tablet a day. I had noticed that it was having less effect in the last 2 weeks.
I’m wondering if my symptoms of the last week were caused by lorazepams tendency to be more volatile and cause ups and downs due to its properties, or the side effects of the double dose of venlafaxin, or perhaps a combination of both.
If it’s the lorazepam, then I may now be in some kind of withdrawal from that, although the diazepam has now replaced it so hopefully my symptoms should soon stop.
The next challenge is to taper off the diazepam assuming I cope with the new regime.
One thing is certain and it was not the pregablin making me feel worse (I only took this for 5 days as per note last week).

Ho hum, what a rollercoaster, but I still have to believe that the venlafaxin will start to work soon.

It's mostly from the venlafaxine dose increase, imo. A 37.5mg increase for a week would have been kinder.
