What Causes Severe Mood Swings Along With Anxiety And Depression?

Good Afternoon, I m a 31 year old female who s been relatively healthy most of her life. I ve been experiencing constant mood swings and bouts of anger and depressed emotions more and more lately. I ve already been diagnosed with Anxiety disorder and was on Zoloft for almost a year, but I didn t like the way it made me feel. I ve been off the medication since November, but have gone through a significant weight-loss since the beginning of the year, healthily by the way through controlled diet and exercise. My body is in phenomenal shape now; however, recently I ve been having suicidal thoughts quite frequently over the last few months! I get upset more frequently, and my husband has been quite worried about me because he s not sure what to do. Knowing that I have anxiety disorder and that I feel depressed lately, I m worried that there could be other underlying issues that I ve not dealt with yet. My dad is OCD, and I have bouts of OCD quite often when dealing with the anxiety and depression, especially when fighting with my husband...I go round and round and round and won t stop until there s some form of resolution, even if it s one I ve come to before. I m incessant and can t stop it or can t turn it off! It s terribly frustrating for both my husband and for me, and it continues to make me anxious and sad because it s not stopping and isn t going away! My husband said he thinks I need to have something on hand like Xanex to help me when I get to this point, but I don t know what to do! I m so confused if I need to try to get medicated again because I don t like having a sense of out-of-control feeling when it comes to my emotions, but I also don t want to have to be medicated for the rest of my life! Any suggestions or help you can offer would be fantastic, as I m worried about what I might do next. I don t want to hurt anyone else in this process, and I just want to be okay. :( I m guessing I need to have a more serious talk with my doctor to see what else can be done? Thanks in advance for your help or advice. Sincerely Grateful, Anna Bevins
