How can I accept that no one will love me at my lowest?

so I lost weight i was overweight my whole life and now im skinny , but now there's this guy I met he's nice and everything but one day i thought that he wouldn't even be with me if I were overweight , now I know that it's not everybody's type , but it's hard to accept that no one would love u at your lowest point in your life (like being broke or overweight or ugly) and that u wouldn't be worthy of being loved , my boyfriend wouldn't have loved me if I was overweight , so if I became overweight again i guess he would leave me? I don't know , but how can accept this?

How can I accept that no one will love me at my lowest?
