Du'a

assalam,( question would prefarably(not neccesarrily) like to be answered by yasir fazaga)I have been imploring and supplicating to allah since a long time but my duas are not answered. I tried to pray all times even in tahajud.i am down in the dumps loosing faith in allah. I know my allah he is great he could be testing i cant leave him i had been helped by allah in the past very rapidly whenever i was in difficulty. Once i made a promise to allah that i would never do smthing if i did then never ever help me but please this time help me, After that allah helped me but later i could not fulfil my promise somehow i broked. I did taubah and i felt that i might have been forgiven. Brother but it seems to be quite impossible to be truthfull for 24 hours. i make mistakes everyday and i dont expect to be forgiven for all my sins.i know his mercy is more than my sins. what to do everyday my sins are increasing.i ask for duas but no results even if i see results but not on higher level...please for allah's sake pray for me and give me some advise..oh! brother please help me if my allah doesnot want to give me for  what i have been requesting for then please tell me how i convince myself..Allah knows the best...
