Is DD depressed?

[BeeEm]

DD2 is 9.5. i have posted recently in a school thread also behaviour. briefly - since half term she has been refusing to go to school - she has been going but i have had to physically carry her in there screaming. friendship issues dealt with by school - also at around the same time had a tummy bug and was sick. this was about 6 weeks ago. ever since she has felt sick - all she says over and over again is 'i feel sick' she cries, whines, wails etc etc and feels sick. has been seen by Gp - bloods all o.k. Now i've seen the school nurse who thinks it is a self esteme thing which i think is part of it.
i really think she has slipped into a sort of depression. she doesn't eat. has given up all her sports/activities. only wants to sit on my lap. she hates being separated from me at all. difficult brecause i work full time (shifts). has been having tantrums worthy of the most stroppy 2 yr old.
i've managed to get this week off work - am waiting for boss to get back to me to 'discuss' this.
does any one have any experience of depression in children?
i really dion't know what to do. do i take more time off work? do i carry on as normal? school nurse thinks going to school is important structurally for her. is it? am also seeing GP again without DD on thursday - do i ask for a CAMHS referral?
i just want my happy funny girl back.

Has she, or is she being bullied at school?

She did have a few issues with another girl - school jumped on it quickly and all seems o.k now. she says she isn't - other girl is friendly in the playground now - so no i don't think she is. but thanks.
