Speaking as someone who has been through the mental ups and down of life and still receiving professional help... You are making the right decision. Taking care of yourself first should always be paramount to anything else.
Those dark thoughts come on like a wave and stay with you a bit. But when you finally get a respite, however brief, and look at it with fresh perspective, you realize you are glad that you didn't do anything drastic and find things in life that help you move on and keep up the fight.
Being up front and honest about it will help manage expectations from people you are worried about disappointing. If anyone doesn't understand that you are just a single person, then they need to do some soul-searching.
Please take care of yourself and come back when you are healthy and ready, however long that takes. Wishing you success in the journey.

Yes, at least I don't try anything with those destructive ideas that go through my mind, for now at least, I have suffered from depression all my life and I have learned to deal with that. But this time, something happened inside me and I just snapped. Thank you for your words, and yes, I probably need to seek help to regain my motivation and will to live.
