Pregnant and freaking out (long read)

So I had decided to get on birth-control (depo) and did the whole take a test before you got your shot. The test was negitive and I got my shot. Few weeks later I start to feel sick and feeling like I'm pregnant. I have been on this birth-control before and had no issues...

So I did some research and found out that some side affects are similar to feeling like you're pregnant so a few days past and I feel horrible so this morning I took a test to ease my mind... And I'm pregnant.... The worst part about all of this is that I'm already a single mother of two just recently moved in with my dad to save money. The father of this baby knows and he is on board but he lives in KY we have been doing this long distance thing it's about a 3 hour drive so it's not too bad. He just recently found a place for all soon to be 5 of us. I know my ex won't be okay with me moving 3 hours away unless I do the driving both ways... The person that I'm most scared to tell is my mom....I want to have a plan in place before I tell her... So she isn't so mad...

Tell me that it's going to be okay!!!
