Difficulty getting married

Q: I am now 31 years yet can not find a groom. Actually I missed many opportunities now I regret that though I know that was Allah's decree. Now I feel too restless. No inner peace of mind. How can I remove my stress by dua? How can I convince Allah for getting married very soon?

Surrogacy

Q: My question is that if a Muslim man has two wifes and one of them has womb cancer which means that she can't carry a pregnancy. Could the other wife carry the pregnancy for example like a surrogate would if she wishes to?
