At my wits end

Our newest blessings is proving to be a handful. She fusses all day and night. I cannot get anything done during the day almost except maybe some school and a bit of laundry and supper cooked at night .She is up most of the night. I have switched formula, bottles, pretty much everything. He ped. just said she is colicky and there isn't much you can do. I have tried fennel and catnip in her bottle which was recommended to me by a friend but it doesn't seem to help. Gas drops, gripe water, tylenol does nothing. I have done so much praying lately but I just feel so lost. I am so tired but still have other responsiblities, it is not like she is the only one in the house. Last night dh got up with me to help with the 1 yr old also cause he woke up and didn't want to go back down. I am not sure why I am blogging about this, guess I just need to get it out. I am gonna wait a while longer and if she doesn't get better I am gonna ask the ped. to check her for reflux. Maybe it is burning her throat. I don't know! Just say a little prayer for me if you do not mind.
