The amount of work I have to do can be...pretty overwhelming

So, here's my situation. I actually have a schedule for chores, calls and appointments that I have to do. And it'll go on for 5 days straight. Nevertheless it's very stressful so that's why I made a vow that whenever I'm not working, I just eat or zone out in bed or just sleep. That's all I have the time or energy for. I know the people in my life can add to the stress, especially my mom but I know I have to sit down with her and fill out paperwork so I can receive my dad's death benefits and his life insurance. And while it can be hard to trust my friend 100% (she is a feminist), I can see how stressful her position is too (her house is shitty, her and the two men who live with her can't afford medical care or a nice car or a lot of other things, etc). This is just going off of what she told me but I'm giving her the benefit of the doubt. Plus, she does her part to help pitch in, give me financial and medical advice and to help me through this crisis. I was planning to go through all this shit first before I decide whether to stay with her or not (I keep thinking it's kinda manipulative and underhanded for me to do that though but either way if I don't want to stay with her, I will try to make my feelings clear about that if I can. She may be understandable, she may get pissed and get upset but if it doesn't fit, then.....it doesn't fit). Also, I know other than her, I really don't have anyone to really talk to for support or anything. And I do plan on calling therapists and doctors and stuff but my schedule is already crammed as is. Still, I can see how the stress is impacting me so I'm doing my best to take it slow and taking it easy whenever I can. I can tell that my willpower and patience will be tested and I do have to practice on remaining as calm as I can be, especially through the next few days. And a part of me wants to believe that I can make it through these few days but still.....it's an uphill battle.
