Go to the Gurdwara on Princes Street, they have trained and qualified councillors. We cannot judge all Gurdwarey or people by one or two negative experiences. Pinning the blame on Vaheguru is not going to make an iota of difference to him but it might to you in the long run. No one can understand your pain but Guru Sahib is ghat ghat ke 'antar' kee jaanat, they are all pervading so know how you are feeling. From a Sikhi angle Karams are dynamic, so regardless of what we say, like someone else said they all catch up with us but some of their affects can be reduced based on what we do in this life ie losing ego through meditation and experiencing inner peace and calm.
Think about the hundreds of thousands of Shaheeds, the bibis who had their children cut to pieces and placed around their necks or thrown on top of spears, shaheedi of Baba Banda Singh's 4 year old son when the mughals cut out his heart and force fed it to Baba Jee, shaheedian of Sikhs with Guru Tegh Bahadur Sahib. Imagine if they blamed Vaheguru Jee, none of us would be here today.
