Pregnant. Again !

Penelope
So I'm 22 years old and I have a beautiful 5 month old daughter 😌 
And I missed my period for December month and I'm pretty sure I'm pregnant 😔😣
I took like 4 test and they all came back positive. At this point I don't know what I'll do. It's clear that I can't keep it because financial and mentally, I don't think I can have another baby so soon. My boyfriend and I decided it won't be right to have it because of our circumstances. But I still feel guilty having to terminate. I'm not looking for judgements, just advice and how to adjust on such a life changing decision 😔😶
