I do not think I can comprehend your situation, and I might not be able to give you the correct advice.
However, if you start with hanging around with the correct people (who pray 5 times a day), I think that would be a start. Slowly increase your circle of friends, to include more practiscing friends rather than those who are not practicing. As time passes on, you will find it easier to pray, as your friends will be praying as well.
having to make wudhu constantly does make praying namaaz more time consuming and not as convenient.
SubhanAllah, I don't think this was the right thing to say. IN line with the hadith in Sahih Bukhari, that if you do wudu 5 times a day, your sins are washed off from you like dirst is washed away with water.
Narrated Abu Huraira
I heard Allah's Apostle saying, "If there was a river at the door of anyone of you and he took a bath in it five times a day would you notice any dirt on him?" They said, "Not a trace of dirt would be left." The Prophet added, "That is the example of the five prayers with which Allah blots out (annuls) evil deeds."
(Sahih Al Bukhari Volume 1, Book 10, Hadith # 506)
However, I see where you are coming from. If you are a brother, then it shouldn't be a problem - I think the problem is more for our sisters, as they have to take their Hijaab off and perform wudhu. I'm not sure what to advise on this, so I'll let someone else advise you InshaAllah.
May Allah guide us all and bestow His Mercy upon us, Ameen.
