Please tell me this is going to work for him

I have posted about my DH is AIBU last week when his depression reached crisis point and he spent 2 days in bed. He is suicidal and incredibly low. He is waiting to see mental health team next week, so hopefully a specialist will be able to help him.
Dh started on citalopram 10mg in April, and then was abruptly withdrawn 3 weeks ago after having myoclonus/myoclonic seizures. He suffered dreadfully from the withdrawal and has been a mess ever since. GP prescribed Venlafaxine on the lowest possible dose and the jerking came back. Went to GP yesterday and he told us off for not stopping the venlafaxine straight away!

I just don't know what to do anymore. He now has amitryptiline (can't spell that sorry) 10mg, which is such a tiny dose. He has been advised to gradually up the dose daily up to 50mg. I have done a bit of research on dosages and I know that this is not the therapeutic dose for depression so will probably not help him much anyway.
Does anyone have experience of not being able to take SSRIs ? If so what could you take and did it work?
Also I will post this on another thread but we are so worried about his job, as he is likely to be off for weeks and don't know how we will manage if they sack him.

I have been on mirtazipine which was really helpful and I don't think that is an ssri maybe worth investigating?

Well obviously I'm not a doctor, but I think 10mg of Amitriptyline isn't going to do much, a therapeutic dose for depression is about 10x that amount. The side effects will also not make it easier to get out of bed.

Mirtazapine isn't an SSRI. Lofepramine is a tricyclic but with less side effects than Amitriptyline, making easier to tolerate a therapeutic dose. Moclobemide is a 3rd line option that they sometimes use as well.

A psychiatrist would have more knowledge than the GP and perhaps be able to recommend a combination of medication that can help. For example they sometimes use antidepressant + lithium for suicidal patients.
