Ok I just have some questions I’m 19 and pregnant with my first

So I’m 19 and I’m about 10 weeks pregnant my ex boyfriend the father 17 acted weird like when we found out he stoped being as affectionate and stop wanting to be around which led to us separating and I just don’t know if I can raise a kid on my own my mom is a big help but it’s still hard and I want to get back into dating life but with being pregnant I’m scared I’m not gonna find anyone that good for me and the baby or no one will give me a chance because I am pregnant also I get super dizzy which idk if it’s bc of being on my feet all the time or if it’s something to be worried about I just got my first ultrasound and they say everything seems good but I just don’t know and I can’t keep anything down bc I’m really nauseous all the time
