i'm not homeless right now but have been several times in my life.
i don't know your situation, so please take the following as 'take it or leave it' -
if you're here b/c of your current homeless situation and thinking about suicide because things seem so terrible i offer the following:
every time i've been homeless (3 times over the past 12 years) i've been able to achieve a much better situation, including stable housing, job, and more, given time and effort. there are so many resources out there, even if they take time/patience/perseverance to get them. if your current situation is why you're here i recommend giving it some time so that you have the chance to improve your situation.
i promise i'm not trying to judge or to tell you how to live (or not live) your life; only offer my limited experience.
best to you.
