Everything about me. My life. My body. My future.
If things are as bleak as you're making them sound today, then I have one point of good news for you. If you can focus on the positive instead of dwelling on the negative (which is difficult when you're new to it) - you can really take a ton of weight off trying to make an uphill climb.
I've had lots of shit go wrong for me recently - my siblings disowned me while I was dealing with my father's death (and threats from the only close friends we'd made down here at the time [tons since though] - from some people that turned out to be drug addicts) and ending up in the psychiatric hospital. We managed to get bedbugs from one of the string of hotels we used while waiting for the moving truck to get here (or the movers sucked really bad and got them in our stuff mid-move I guess is a possible option too - we were staying in some cheap places though to save money on 10 days of hoteling however). My car just a few days ago started venting some portion of something smelling like exhaust into the car after ~25-30 min of driving that the mechanic can't tell where it's coming from when I drive it over there (5 min away) since it doesn't post a code on the computer and doesn't start until I drive it longer, and I'm not motivated to drive in circles just to get the problem to start.... [tempted to just drive the car into the Banana River and call it a day and replace it, but really don't want to add extra recurring cost/bleed my investment accounts right now]
But you know what, because I focus on the positive and don't dwell on those things - I literally think about them for a moment, let them wash over me and don't dwell on them and they don't bog me down - and people think I'm a happy, well adjusted person to the point where if I literally took up every offer of gaming with someone or other projects - I'd probably have zero time to do anything for myself or the wife alone. [And god help me if I try to work for someone else instead of opening a business (which I've considered as an interim thing perhaps - changing gears on my business concept and this one will take a long time in getting all the pieces working)]
I can't tell you what the best method you'll find to achieve a similar enlightenment - but I can tell you that when you're at the absolute bottom it's the best time to learn because when everything is horrible, it's easy to find constant improvements to give yourself an internal thumbs up to if you can manage it so that once you get the stone rolling, it should be easy to keep it going.
But seriously with how you're doing, start trying everything that you think might work until something sticks - you'll be better for it if you can get one to. (Meditation perhaps? I vaguely recall something you said made me think that's in your wheelhouse)
[And lindz's example of a hobby is part of the whole philosophy I'm talking about - a specific one - but a great one, and some variants take no real time or cost - even if you're a busy student you've always got pen and paper to work on art even if you have "no talent" simple things like making geometric shapes can be quite relaxing and help take you out of the moment even mid-class if it's something you don't need to concentrate on, or between classes if you need to focus completely during class]
