Doubts regarding wet dreams

I think I might be suffering from OCD as I constantly have doubts about everything. In the mornings when I wake up to pray fajar there is still lots of time left after I finish to go back to sleep, but I am always scared I might get a wet dream so I stay up. But this got very tiring after a week because I am still a student and so I decided to go to sleep. The problem is that I constantly or very frequently will worry about getting a wet dream because I used to get them quite frequently before and they caused me a lot of distress and made me have doubts all time and made my life very stressful and hard to live. So now every time I am going to sleep I am always worrying about it and sometimes I do get a wet dream I think (I don't know for sure if it is a wet ream because I have been told that a wet dream must contain an orgasm, and I never remember having one) in the morning it is very hard for me to know if there is extra wetness because I always have some vaginal discharge. The day before I was getting a lot so I couldn't tell this morning. I decided to do some research on it and found a female Muslim's article and read it and it says that I must have certainty that I had an orgasm to make ghusl. But since I suffer from doubts a lot all the time it is very hard for me. Before I would just make ghusl even if I wasn't sure but that caused my doubts to get even worse because even the smallest doubt I would go take a shower and make ghusl. My mom is very upset with me and gets angry if I take so many showers all the time So my questions are:

1) What do I do in these situations? I am a very doubtful person and can never tell. Do I just make ghusl every single time then? This caused me a lot of hardship in the past because I have many doubts all the time.

2) When I woke up this morning after having a wet dream I didn't remember having an orgasm and I didn't fully remember the dream and couldn't tell is there was extra wetness because I was having lots of vaginal discharge the day before so I didn't make ghusl. I had to go to school so I changed my clothes and when I came home I did wudu and prayed namaz, but then I was having doubts again. Did I do the right thing this morning, because I have done a lot of research and they always say unless you can make a promise to Allah saying your wudu has broken it hasn't, so since i wasn't sure at all I thought I would try to stop my doubtful thoughts by not doing my normal routine showering but then I just got more because I keeping thinking what if I did the wrong thing.

3) How can I over come these thoughts? They have controlled me for 2-3 years and they make doing simple things like namaaz and wudu very difficult for me. So do I still need to do ghusl even if i am not sure I had an orgasm in my wet dream at all? Are the clothes I wore to school napak now? Did my namaz not count?

4) After I went to the bathroom this morning to use the toilet before school I washed myself like I normally do after I urinate but there were drops of water after I got up from the toilet from the water I used that touches my clothes. Are my clothes napaak because i didn't do ghusl?

5) If I sat somewhere with those wet drops in my pants did the place like sofa or bed become napaak?

6) If I have wet dreams in the future when I don't remember them and am not sure if there was an orgasm and can't tell if there is extra wetness because of vaginal discharge what do I do becuase they happen frequently and when I wake up I am very sure I didn't have an orgasm because I don't remember having it at all but then my doubts start and I begin to worry that I am always making a mistake?

7) Since I didn't shower until the next day, did all the clothes I changed into get napaak too?

Please help me I am very troubled with my life right now. I think I have gone crazy. Thank you for helping me with my doubts may Allah reward you.
