I'm thinking of putting my one year old and three year old up for adoption
Why do you want do put your children up for adoption? Can't you care for them?
No, I  am just overwhelmed looking after them.
It is better to put your kids up for adoption instead of abusing them. If you need help you can reach out to people or organizations for relief.
Why are you giving me so much crap. Sometimes I feel no one cares.
It is perfectly normal to feel stressed out, especially while raising two kids like yourself. You should find a day care or a babysitter so that you can have a break. Try to find time for yourself and it will help alleviate the stress.
