This is terribly sad news.My thoughts are with his family and friends.I hope anyone here feeling down about this or things in general should try to make their feelings clear to others and maybe get some help or an ear to talk into.
I also suffer badly from depression and have the scars to prove it both mentally and physically.I have also been down this road but recovered due to intervention.
Sometimes things can look bleak enough that a final rest seems very much the order of things.Things do improve,although i doesnt happen overnight it can if you can accept things will change.Sometimes just the realising of improvement is all it takes to make the physical changes inside the brain.
It isnt easy to know what is going on in a friends subconscious and they do make attempts to hide their true feelings.One thing is you must not blame yourself for not txting ,phoning or visiting.It likely even on the day you wouldnt be aware of any problems,usually its quite the reverse when youve made up your mind.Therefore impossible to know or act and in that im am certain you would have jumped readily to this chaps side.
..thanks for being so open on a very personal and sensitive subject..you are a topman 
RIP
