Stomach and Sexual Problems- Marriage is near please help

Dear Doctors out there,
I Hope and pray you all be fine.
I am Male 31
Height 5 10
Weight 68 Kgs
My marriage is in a month and i am facing problems that are making my life horrible. I have very short time, Please Help me out.

My Problems are quite old and i am unable to get rid of them though i am working hard.
I will try to brief things now.
Stomach and Sexual issues:

I have bunch of digestive problems. Milk, Butter and Ghee disturb stomach. Sometimes i get loose stool , sometimes Loose motions. I have to convert to simple foods like Yogurt, Bananas and rice to Normalize my self. Chickpeas, Daal Chana, Red meat also cause the same problem.

Fried Fish/ red meat , Almonds/Nuts, dates not only disturb Stomach but also increase precum discharge, semen (Whitish) discharge in urine. Sometimes Night fall Occurs with little sensation the night i eat these things. Headache/stammering immediately after meal. After meal I feel confused , unable to process information properly that remains all day. The day I dont do breakfast I feel more mentally clear till lunch.

Talking about my sexual problems:
I Face Precum discharge with little sexual exposure, talking with my fiance, explicit material on internet or merely sexual thoughts. When i dont wear underwear the friction of Pants or Pajama with Penis Excites me and cause precum leakage. I Always wear underwear now since many years.
After engagement i had few close time with my fiance. Once i spent my whole day with her, hanging out . That day i had abundant precum discharge and next day i feel hell of weakness and fatigue. Similarly after every meeting with her i face precum discharge with weakness to follow. Once i had little more Close time with her and I got discharged with little Touch and rubbing. That was very embarrassing and shameful.
Fish , dates , nuts, honey , eggs etc that are considered good for sexual weakness cause not only excessive precum/ whitish discharge in urine. Also cause Nightfall. I feel jerks and sensation of dribbling of something.
Erection is sometimes good but sometimes weak and short lived. Minor erection followed by quick precum discharge and erection became soft. I dont think this condition is good enough for making sex. No morning erection or weak erection. A week ago I ate two figs in night that night I feel morning erection with precum.
I used to masturbate and then beat myself for the wrong doing. I have lot of guilt and fear of this Problem. I blame all my life suffering to this disorder.
Physical and mental contdition:
I feel lethargic and fatigued all day. Wana lie down and take rest. Pass whole day in office through my determination and will power. Weak memory, poor IQ, forgetful Confusion and nervousness.
I have left all my bad habits since 6 months. I am exercising, Doing kegals , Yoga exercises for stomach and sexual problems.
Previous medication:
I went to allopaths and they gave me Some meds to stop loose motions and SSRI(Estalopram). Effect is short lived. I used Kali Phos 6 x for 1 week , 4 tabs in morning and it disturbed my sleeping pattern and I left. Lately I am using Schawabe PTK. 40 with the idea that it will make my semen and precum thick and Slove my problem but it increased my nightfalls . I don’t used to get nightfalls. But PTK 40 has started nightfalls, Qucik discharge without sensations. It made my problem even worse. In last 30 days I had 5-7 nightfalls without erections. I used Lycopodium 200 before. It made erection good by not lasting effect. Before that Nuxvomica 200 was prescribed to my by some doc that made my stomach conditions good for 3 4 days.
Please , Doctors are live savers. Please save my life. Please prescribe me medicine , advice me that make me fit for marriage that is due in a while.
I kept hope that its never too late if i find good hands. I never left believe in Almighty.
Anxiously waiting for reply.
