Introduction & help

Hi, I'm k8rsgonnak8. I'm a 24 yr old female who was diagnosed as Bipolar last year in October. I did therapy for about 6 months then decided I was ready to take on life on my own for a while. I enjoyed the therapy but wanted to be able to work through my problems on my own. I felt like I had worked through the major ones and had figured a lot out. I began taking Lamictal (started low at 25mg and then upped to the max, 200mg, after a few months). I have been on it for over a year now. Started in October 2014. I have really enjoyed it and think it has helped a ton day-to-day. I feel like my brain has calmed down and I don't have my mind racing a mile a minute all the time. I sleep better, am calmer, and am happier. But after a year, I still feel that when I am upset/mad I get uncontrollably worked up and more than is normal for a person of my age. I often worry about everything and catastrophize every "bad" situation. Example: I thought my boyfriend was in a hospital or dead when he texted that he was on his way to work, then didn't text me for an hour or so. I do this a lot. It is a pain to me and him and anyone else intimately involved with me. I also am known to get very down/depressed and often get very up. I have a past of self-harm and suicidal thoughts but haven't really had any of that going on for at least a few months.

I had my check up with my psychiatrist, who I've had for about a year now, and after giving her updates on how I've been feeling and thinking, she decided to put me on Zoloft on top of my 200mg of Lamictal. I am starting for 2 months on the lowest, baby dose at half a 50mg pill a day before I go back to see her Jan. 22. Any advice on this? I'm a little worried about getting on more meds and on top of my other meds. I also have heard bad things about Zoloft. Any advice, thoughts, etc. are much appreciated! Thank you! :)
