Help! Should I go through with it?!?

I have an 8m old baby and just found out am pregnant! Idk what to do! Having mixed emotions- I'm afraid of failing and going into depression if I go through with this pregnancy but on the other hand it's also a BLESSING! Please give me some advice! I have no family or friends around since moved out of state but I am a SAHM. I'd love to hear everyone's opinion on both sides! TIA!!!
