I can attest to the fact that the DSM does not say anything about removing someone from their home for any reason other than hospitalization as a part of treatment. If it does than I missed a section.

As to why it will take 2 months for her to get "better", that is simple. Antidepressants typically take about 7 to 8 weeks to achieve effectiveness. Usually during this time you would want to have someone around who can keep an eye on the person because as the medications start to work the chances for bad things happening increases for a little while. That passes and hopefully the person is getting the full benefit of the medication.

However, it can take longer than 8 weeks to not only find the right medication but the right dosage so that doesn't sound right. Even more troubling is the fact that any half way competent degree holding mental health professional knows da** well that if you can help it you do not want these people left by themselves when they first go onto the medication.

A typical case would be for the counselor to have both of you in so they can make sure that you both understand what will happen after starting the medication. It would be important for them to explain to you the risks, things to watch for and so on so that you can keep an eye out. Also during this time it is usually the case that the person go in for regular sessions to help them keep going on the right path until the medicine reaches the point of being effective. After that continuing therapy is considered if there is benefit to the patient or if they feel that they really need to continue (in which case it is probably better to keep seeing them).

Anyway, if nothing else I would at least place a call in to another counselor and see if this sounds right to them. I am pretty sure it wont but a second opinion doesn't hurt. If they say what I am sure they will say, that there is no reason to have her in an apartment by herself and that it might be dangerous, I would pull the plug on the whole thing and find a new counselor for her.
