How to cope with anxiety and feelings of hopelessness?

You have belief in a higher authority, so keep praying to God to give you help and guidance, ask him to ease your burden and help you with the anxiety to get through this time of stress you are experiencing. God tests his followers, so you are in a test which you must endure through to get to the other side. These tests always take much longer than we humans would like them to take (been in a few myself, still in one, have great empathy for your issue of anxiety and sometimes feeling hopelessness) but God has some purpose for them to help you grow as a person and develop a higher spirituality and maturity. But that will only happen if you make the effort to develop the relationship with God and follow what he wants you to do. I cannot suggest a magic cure, there are none, but I hope this was helpful. Endure, persevere, keep working on yourself (your thoughts, your beliefs, your morality) until God changes the situation.
