Going through it and feeling like there’s no light at the end of the tunnel

I am so overwhelmed I cannot deal any longer. I’m just crying and an emotional mess and it’s ridiculous but I can’t control it. Things are just not going well, there’s obstacles popping up everywhere. I can’t make anything work and things keep getting worse by the day. Time is running out on deadlines I have and I can’t get the pieces to go together. I’m losing sleep and my thoughts are just not helping me at all. I feel like I’ve let my family down and feel like I’m just feeling sorry for myself. But it’s not healthy in my brain right now. I’ve talked to my psychiatrist and therapist we’ve tried a few things but I feel like until I get this stuff all worked out things won’t get better or more manageable. Please if you have things that have helped you when you feel hopeless please share them!
