My ex has a vitamin B12 deficiency, and when you're low it will certainly aggravate depression. It is quite notable to someone close, at least in my case. Anyway, if you're prone to depression its good to make sure you're at a healthy level of all your physical needs. Vitamins, minerals, sugar levels etc.
I fought against medication for a long time, but now I take some, and it makes a tremendous difference (in a good way). It wasn't a very easy process for me. It took about 5 years to find something I was comfortable with. But, I'd strongly agree if your doc is recommending it. Side effects are certainly a thing, and can be problematic, but if you can keep track of all that it will really help to find a good one for you. It's a risk/reward thing I guess. There's a big reward, I think it is at least worth a try. Anyway, all the best. Take care!
