I am suffering from depression recently. All was going well in my life like minor problems were there but it was not a issue. I am in a serious relationship from 2015 with this girl all was good in first 2 years but now I got to know that she was cheating on me for last 6 months with the friend of her. They both were in a physical relationship. I and the girl was also in a physical relationship. I want to forgive her as she has promised me that this will not happen in the future again but it's like a shock to me I am not able to move on from this but I love her and all my family members know about her but I didn't told them about her cheating. Please tell me what should I do I am unable to forget all this. Suicidal thoughts are always there in my mind since she told me about all this. Please suggest me something if their is some medicine or therapy to help me out. I desperately want to forgive but whenever I sit alone for even 10 sec this thing always strikes me. Please help me out.
