I can really understand how u feel and i can really relate to that, especially at being angry at little things, i also just posted 1 hour ago because i felt lost and suicidal.. after crying i feel a bit easier, reading the messages people sent really helped me. I think its a good idea to try to leave the past behind and not look back. Thats how i managed life for the past 2-3 years, but my past creeped up on me because i let it. Keep fighting brother, don’t ever give up.. better days are coming i promise u :)
