What am I getting myself into...*Double Topic*

Ok so I have two things I wanted to vent about...but didn't want to make two different topics.
1) One of my good friends is almost 5 months pregnant. She has mental health issues aswell and takes medication. I believe she is off all her meds due to being pregnant. She has a 5 year old son who is living with her parents because she wasn't ready to raise a baby. She got pregnant this time because meds she took made her BC less effective. The pharmacist didn't tell her about that.
So...basically she is having major issues with her bf, who she has only been with since November of 2012. He is emotionally abusive and to me, I don't think it'll be long before it gets physical. I'm trying to get her to leave but of course she is torn about giving him another chance. She said she feels trapped. She has said she would rather give the baby up for adoption than parent alone. I said IF she wants to raise the baby as a single mom, she can move in with me and I would help her, seeing as I raised my daughter so far as a single mom.
Am I getting myself into too much? On one hand it could be a good thing but I don't know if this could cause more stress for myself. I guess we'll see.
2) I babysit 3 days a week and work at a fast food place 3-4 days a week. I have been babysitting this little girl for almost 2 years now and her mom just told me they are moving back to their hometown, which is out of the province. So, as of June 6th (Happy Birthday to me BTW) I won't be babysitting anymore. I have been wanting to do the home daycare thing for awhile now, I did it full time almost 2 years ago but then lost all the kids I babysat and couldn't find anymore so went back to work part time.
Now, I don't know weather to still try the home daycare (still unsuccessful finding kids to babysit) or go back to a real job. A home daycare would make a lot more money, I would get to be home with my daughter and it would be a lot less stressful than dealing with my current boss.
On the other hand, it's not guaranteed, and I could be without income if I lose the kids I babysit again.
I also won't get many hours in my current job, probably 25-30 and I need at least 35 to pay my bills but I would prefer at least 40 which is highly unlikely. If I go back to a full time job, I need to find another job.
Help me...I don't know what to do.
I truly believe things happen for a reason...it's just hard to see what I am meant to do right now.

Being a single mom is hard! I see my mom struggling daily and we are three girls and I'm the eldest. We make just enough money to survive and she is stressed a lot! But if you do help your friend, she can also help you! You can both get a part time job so that one can stay at home and watch the kids while the other one is at work... That's if its possible to find a job that would make it that easy... It might be more stressful but depending on how old your daughter is, she can also help take care of the baby... If you can maybe get a few kids to babysit, you and your friend can babysit them and take turns when your not at work even if its just 2 other kids. Every bit of extra income can be useful, since raising a baby is very expensive... Its just suggestions because I am not and haven't ever been in the same situation. But I hope you will find something that will work for you and that you can find the help you need! Best of luck to you!
