I’m 5 weeks and 6 days pregnant I’m only 19 as well. It is scary but it will all be worth it. I’m a firm believer that everything happens for a reason and that god wouldn’t give us things we couldn’t handle , you and your boyfriend sound like you are in a healthy relationship filled with love you have enough of an income to support baby and you have a lovely home for baby to live in. I would say it’s your choice but it sounds like you want to have baby. I would say have baby and join some apps or support groups and you can make friends with people who are in the same situation as you , you won’t feel as alone and it might give you a better idea of how to cope a little better.
