Depression and guilt symptoms and conditions

I've been on Bupropion XL 300 mg (Generic Wellbutrin) for almost 3 months.Overall I feel much better than before.I can cope with lifes issues without freaking,I'm a better mother to my girls.I haven't had any major side effects such as hives or hair loss,however I do notice occasional bouts of anxiety.Tightness in the chest.My libido all but disappeared after having my second child and I'm only 30 years old.I was hoping the Wellbutrin would help but it's really made no difference.Aaargh! But at least I don't have to suffer the depression and guilt due to lack of sex drive and the monotony of everyday living.I'm living my life again...And my hair has never looked better!
