I had my gastic sleeve done in feb 23 2012.

I have been very sensitive lately.

I went to work today and started crying for no reason.... I am wondering if this has happened to anybody else.

You had your surgery last February? Most people have the hormonal issues way earlier in their journey than this so I want to double check.

I just goggle it and its provably b12 insufficiency. I haven't been taking my b 12 I just never thought crying for no reason will be a symptom

Amazing how Vitamin deficiency can wreck havoc on your emotions. I had a combination of Vitamin D Deficiency and Hypothyroidism. Get your Vitamin D and Thyroid checked. I got sloppy with both and started to feel weepy. I got back on track and the symptoms were gone within a few days.

Also check with your doctor on your B12. I have known a few people who found out that for some reason they can't absorb B12 anymore and have to get a shot once a month.

Just a suggestion. Take care.
