There comes a time in our lives where we transcend into a certain age and stage where we have a hard time dealing with our everyday life. We tend to push or be pushed to our limits and we can't cope with it. So the best practice is to take a good rest, revise a strategy to recover from what cause these anxieties. Choose a path that you feel comfortable to achieve and be in control of your life. Stop thinking too much! It isn't helping.
Best is treat everyday as a challenge whether its a failure or not, and teach yourself to accept life as it is to continue. We all face failures and its a human reaction to feel sad. Everybody does. Failure teaches you to make up to your mistakes and you have to thrive to overcome it to survive on your own or with other's help. Ang ibig kong sabihin, kung di mo kayang mag-isa, magpatulong sa iba - sa pamilya, kaibigan, kamag-anak o sa pinagkakatiwalaan mong mga tao. That's the way of living. No man is an island eka nga. Sinasarili mo yata. Gawin mo lang yung kaya mo muna pero don't stop trying even if you fail. Ganyan ang diskarte sa buhay. Diskarte, tiyaga at lakas ng loob yan, kaya huwag kang bibitaw. The moment you stop and prolong that drama of sadness, it brings you to a state of isolation, loneliness, and all negative thoughts comes pouring in and possibly thinking of ending your life. But do you really want to? Is suicide your option to erase these thoughts? I'm sure it is a NO since you are not crazy! You're just in a fragile state, like a lonely kid lost in transition. Cheer up! It isn't the end. I'm not religious but if you are a believer, the Bible can help you in some ways to do it right. But you need to face reality like everyone else and help yourself to move on. Ask yourself what you want (your goal) and take your time to fulfill it slowly at your own pace to satisfy your needs. Whether you fail or not, just learn to control that "static" feeling of sadness and guilt, shove it away, rest, calm yourself, modify and try again. I don't know exactly what your problem is, but you need to gain your strength to go out, prove to yourself that you can change for the better.
