Hello and welcome to PC. I hope things get better for you soon. I sincerely feel that if you get diagnised you will feel better with your mood swings, also I would suggest a physical to rule out and physical reasons for your depression ( I have hormonal depression). and therapy so that you have well rounded treatment. I take medication for depression and I function at a very high level, and I feel that if you get the treatment you need you will hopefully feel more in control and more functionable. I am very glad that you have found this site it is very informative and supportive. Take care sincerly Soidhonia
