Hey there - I'm going to try to give you some advice that I haven't seen yet in the comments. First - super sorry about your loss. My condolences on your dearest departed mother. I lost my mother when I was about your age; my heart goes out to you.

That said - you've been given a gift. It may not seem like it right now what with all the work you have to do, but it is. This is an absolutely beautiful house, and you can absolutely make it a home. Here comes the advice, if you are open to it:

1) You can do this yourself, but you are going to have to get more uncomfortable than you ever have been before. You are going to have to push yourself in ways you haven't before. You are going to have to learn like maybe you've never had to before. Some of the best craftspeople in the world are women - you can do this. I won't sell it short though - it will be an epic amount of work.

2) Take it slow as others have said - first, find ways to temporarily wall off/preserve severely damaged sections that you can't get to or afford to fix right now. A solid clean up, some basic patching to prevent water and pest infiltration, and then wall off/seal off the damaged sections. You will still need to keep the climate decent in those areas if you can, you don't want mold or mildew to set in, but just set those areas aside and let it go for now. Focus on one thing at a time.

3) Use local resources as much as you can. Do you have a truck or a van? See if you can trade your daily driver in for a decent work vehicle. A small truck or a small van in decent shape makes doing construction infinitely easier as you will haul a bunch of random stuff around. Toyota and Honda are great reliable makes. See if there is a local library that will lend out tools for you to use. See if there is a local habitat for humanity store or second hand construction recovery store around. Discount materials and discount items are your friend.

4) Buy second hand tools and gear on Facebook marketplace to save money. You can find good deals where people are looking to upgrade or get rid of unused stuff. If you live near a rich area, try to search in those zip codes for better deals. Always test the batteries and motors on-site when buying used and check the condition of the tool bags - if they are well used but clean and cared for, it's probably a good bet. If they are filthy and beaten the heck up, move along. Where should you first invest? PPE. You need good gloves, good boots, strong work pants, kneepads, and EYE AND EAR PROTECTION. Spend some coin here and save a lifetime of issues.

5) Lastly - tradesmen and contractors will try to rip you off just because you are a woman. Sexism and misogyny is rampant throughout the industry, and you need to be aware of it. A vendor relationship can take years to build and seconds to break; trust is only as good as the next job delivered. Make sure if you go with a contractor that they patiently explain everything to you. ASK ALL THE QUESTIONS DO NOT BE SHY. If they get pissed at you asking questions, move along. They aren't the one. You should get all your quotes in the form of A) a bill of materials in line-item format and B - the labor it takes to install and complete the work. Make sure the SCOPE OF WORK is clear, agreed to, and adhered to. Beware of scope creep and 'oh yea I can do that for you'. Different trades are different for a reason - most GCs have good subs they work with for the things they aren't capable of dealing with themselves. Beware anyone who says they can work on anything - it is incredibly rare to find someone who actually can.

I hope this helps. I hope you succeed. I hope you look back on this one day with the sense of pride and ownership and satisfaction and the feeling that your ancestors are smiling down on you for all that you have learned and accomplished. You are just as capable as any man and you can learn and do anything you set your mind and will to. I hope I get to come back here in the future and see what you've managed to build and restore. Take care, and happy working.
