Negative thoughts

Q: I am trying to feel close to Allah by not committing sins like avoiding porn and not mastrubating and not listening to music but the thing which is disturbing me is Shaytan. Shaytan is putting anxiety in me by making me think that I became pious. I will die soon. My health anxiety is disturbing me and I keepthinking that I may suffer from a heart attack, cancer, etc.

I am trying and I know it's Shaytan but over time it becomes miserable for me to bear that negative thoughts are circulating in my whole body. Please make dua for me and suggest a short wazifa to get rid of the waswasas and other thoughts from Shaytan that are overpowering me.

Being grateful to Allah and asking for assistance

Q: I made a request and alhamdullilah it was granted. When I performed istikhara each time I asked I got a negative answer. I asked Allah for a sign and I recieved a message on my phone from Quran Messenger that hardly sends videos and texts... "oh you who believe remain stationed" My heart sank again I asked and the same I received. I asked again and another ayat... "and your Lord is going to give you and you will be satisfied" then I would ask again and another ayat "verily with hardship..."

While walking and that moment I would meet someone who would say... "it will get better and Allah will make it easy"... I'm not sure because I'm not a pious person and I don't believe that I'm special or deserving enough to expect a sign from Allah. I think to myself it could just be a coincidence. Even before I started where I am currently and I made istikhara, a person would say "good luck and Allah make it easy" and I would wonder how he would know that I'm not happy being here.

My heart feels depressed. I'm not sure what I should do but I feel that if Allah wants this for me then I should stay. How do I ease my heart and not be ungrateful or unthankful.
