I'm familiar with that passage. It does not say what you are trying to make it say.
'Why did you make me like this?' does not say "Why did you make me just to throw me into Hell? It does say "Like this", indicating our flaws and weaknesses that we must deal with and overcome to follow Christ.
"Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?"
Common use does not indicate the purpose of being thrown into Hell. It does mean one who follows, rather than one who is destined for "noble purpose" like Paul or the other Apostles.
In that case, you have reason to boast...
Nope, I don't. Christ does all the work. One does not boast for merely accepting a gift or following through with a covenant.
