Impurities on the body

Q: I need to know if I had a wet dream during the night and in the morning I realise that in between my fingers theres a bit of sperm. I'm not sure if it touched my bedding because I see no sign of it on the bedding of course my hand did move around during the night. What do I do?

Q: Being the doubtful person I am I have gone to extremes. I keep washing or cleaning everything. I was washing my hands and the sink had slow drainage so water was collecting in the sink and slowly getting drained. The water collected I felt that a few drops splashed on my arm. Now I am not sure if it actually happened as I didn't see any water drops but may be there were as I felt them. I wasn't able to clean my shoulder and my hair touched that area. Did my hair become napaak or did I become napaak? As the water was collected in the sink and slowly draining and people wash their dirty hands and impurities in the sink but this water was collected while I was washing hands. Can a few drops make me and everything napak. If a person drinks alcohol and then drinks water and doesn't brush or wash mouth and keeps eating 2 3 meals etc does their hand and the plate they are using become impure? I have become so finicky that when I see something wet on floor I presume it to be something impure. Like urine or vomit or impure water. I went to a restaurant and I saw wetness there I don't know whether that was water or alcohol etc and I feel like it touched my feet etc though it didn't and these thoughts keeps haunting me that what if I don't wash. I will make whole house and everything impure. Please help me.

Q: If the inside of the nose gets napak with blood or you accidently touch the inside of the nose with napak hands without thinking because it itches how shall I make it paak?

Q: I used to consume alcohol some time back. Now I have repented and asked for forgiveness as I was misled. I want to know that I was not very cautious about purity and I used make up and make up sponges etc. I have even used lipsticks after consuming alcohol. Now I am in doubts. I have thrown away the lipsticks I was sure about but I have to think very hard that whether I used the makeup sponge over the lipstick or did I use the powder over it and I keep doubting that whether I used a powder or sponge over impure lipstick. Where did it touch where did I keep it and keep cleaning those places. I cannot remember everything clearly. Should I just stop thinking and just use the makeup I have and not over think or worry about being impure or should I think over it. This thinking has really affected my life and I am feeling if I use my prayers won't be accepted and I will be impure. I'm feeling devastated as if there are no answers and I just eventually have to throw away everything.
