Welcome to just answer.
First of all I would like to tell you that you need to cheer up and YES there is still hope for you.
Your fractured fillings or teeth (if there is at least 1/3rd of the crown (upper) portion remaining) can be restored and crowns can be given. If there is little or very minimal tooth structure remaining than the best would be to get them replaced by artificial prosthesis such as bridges, partials etc. Any broken tooth/teeth which is infected should not be left unattended can cause infection thereby giving rise to pain and swelling.
With proper brushing and flossing you will certainly have excellent oral heath (teeth and gums) but whatever damaged has taken place is irreversible and it needs to be taken care.
I am sorry to hear about your discomfort. Please don’t feel sad or low about your situation as you can surely be helped and you can seek all the treatment such as root canals ,fillings, crowns etc without paying too much.
