I was a weak atheist but found myself forced to turn to faith (for reasons I cannot discuss here). I have a need for God to bring meaning to this life.
Just like 99% of people who take up religion.
1) My girlfriend left me so I took up religion
2) I have no real friends so I took up religion
3) My mum/dad died so I took up religion.
4) I lost my job and am broke so I took up religion
5) I'm an ex drug addict so I took up religion
And like you most will not admit why they took up religion but just say there was a very good reason.
If it gives you the strength to cope then crack on, but at least be honest about it.
