I'm (22M) who on the outside leads a normal successful life but on the inside ever  I've been dealing with depression majority of my life. 

Background: I graduated university at 20 with an engineering degree debt free and quickly found a job in tech that I've been in paying almost 6 figures. I lead a healthy life style, workout 5-6 times a week, and was an athlete growing up, so I have a very healthy body. I have a few close friends that I hang out with and really trust and a very supportive accepting family. I've always been told my looks and body above average and received compliments from people, and I believe it because I've been approached by multiple women shooting their shot at me and I've been able to pick up girls I found attractive most of the time. 

On paper, some would say I should just be thankful for a blessed life and to get a grip because others have it harder. I'm very thankful and always pray to God thanking him for his blessing on me and whenever I can I help the less fortunate. 

However, inside my head the only thing I feel is emptiness, sadness, depression, feels like I'm locked in a cell and can't get out. I have no passion or ambition for anything, and cannot come up with "goals" or motivation to live towards. I hate my job and working in general, and the only reason I picked this job is because there is nothing else that I'm passionate about doing in life, I've tried, so I mind as well make a good amount of money. Whenever people talk to me about something, I feel nothing towards what they are saying and deep down don't care at all about what they are saying. I used to play video games and watch TV to pass the time, but nowadays I can barely sit and be interested for more than 20 mins. I try to hang out with friends or leave the house as much as possible to pass the time, but majority of the time I have no interest in anything going on and just want to leave. However, when I sit at home I want just want to kms. The only reason I haven't ended it all is because I'm a practicing religious person and don't want to go to Hell. I've never done drugs, smoked, drunk due to being religious so I'm sober 24/7. Each day feels like hell inside my brain and I check the clock a lot thinking at least an hour passed when it hasn't been 5 minutes. I don't know how people can live till they grow old, I can't even stand living till tmrw. I can't imagine myself living a few more years like this because I think I might honestly go mental. I just want to die and stop feeling the way I feel but religion is stopping me. What do I do?
