I'm feeling lost. I know what I need to do or what I want to do but I seem to stumble at the first step.

School is over and I had a lot of stuff planned in the summer to pick myself up, improve myself and what not. It's not like I haven't been doing anything, I've been keeping up with a few of my goals, but only a few. I feel I haven't been doing enough and I'm running out of time. My mental health is getting worse as I beat myself up over it and as each day goes on I feel more and more lost and hopeless. I've a month left to sort my shit but I feel I can't do it without advice, even reading through threads upon threads feels like effort.
