This is a long story, and I guess I need to vent. 

About six months ago, my ex-fiancee broke up with me without an explanation. She just texted me that she wasn't ready and wanted to end things. We dated for a total of 4 yrs and were engaged for 7 months getting everything planned. I didn't ask for an explanation because I felt broken and was scared of the reason for that to happen. I started drinking a lot. I looked for support with siblings and friends. I feel more calm now and I have stopped drinking as much as I was. I'm 25 and about to graduate with a Bachelor's in Mechanical Engineering. I have job offers, and even have an interview with Tesla. Everything is great, but I still feel empty. I feel like I'm just going through life but don't live. 

Any advice on how to deal with this situation? Of course I suffered depression and had suicidal thoughts... but I don't really feel that way anymore. I just don't know what's going on. 

Thank you.
