Will vertigo symptom go away due to withdrawl from zoloft & lithium?

I am on zoloft and lithium for my depression/anxiety. I was not able to make it to my doctors appt. due to my schedule and financial issues (I didnt have anymore refills left). I am having horrible withdrawl symptoms such as: crying spells, anxiety, being sleepy, weak, nausea, vertigo, etc. Whats bothering me the most is the vertigo. I have trouble walking at times and I stumble a lot. I cant look side to side or up and down without my balance being thrown off. Its getting harder for me to function especially at work. Will these symptoms go away? If yes, how soon? I will be going back to my doctor soon. Please help. Thanks.
