Trying to lose weight but never feel full?

After i had my baby almost 2 years ago, i lost most og the pregnancy weight.But then,when my husband went back to work and i had to be the stay at home mom,it started creeping back up.After i started working a few months ago, my weight stayed under controlled,i even started losing weight.But about 2 months ago, i was out of a job again since i had to care for my daughter andnow its going back up.The thing is, i never really feel full.I try to eat a balanced meal but it never seems like enough.I get these "hunger" headaches and i get really fatigued,i even feels like i'm slobbering(i over-salivate)Could this be psychological b/c im bored and anxious looking for a job?(Which i am,b/c i hate staying home)or could it be something physical?Most importantly,what can i do to stop it.I dont want to gain any more weight,in fact i want to losw weight.Please help!! Any good appetite suppressants anyone might recommend?
