Remember that marriage is a provision from Allah just like other things in your life so remain hopeful. Invoke Allah and privately ask Him from His favors and at time where du'as are more like to be accepted; the third part of the night, during prostration, on Fridays between 'Asr and Maghrib or the last hour of the day. Don't just say 'O Allah, bless me with a wife/husband' but be specific by asking Allah to bless you with someone that He is FIRSTLY pleased with and that will become coolness of your eyes. You don't know who will be khayr (good) for you so don't limit yourself to trivial requirements such as asking Allah for a spouse with a particular height, status, race, nationality or lineage. These should not be deciding factors when choosing a companion for the dunya and akhirah.
