Trying to love the present.

[kristina]

Whenever I try to be fully present, it's like something's weighing me down. It's hard to describe. I go for meditation walks and it's this constant feeling. It's like a general unhappiness or dissatisfaction, mixed with loneliness and... I dunno, some sort of uneasy feeling. I'm not sure how to describe it though, or what's behind it...

Definitely sounds like resistance. If this were me...and it's not, but let's pretend. I wouldn't do more than 5 or 10 minutes tops at your meditative practices and if I were walking, I would notice everything including every thought that slipped into my cranium.
You've got this! I think you're putting too much time into it. Relax and treat it like your guitar...one string at a time. Learning the cords but slowly so that you can enjoy what you're learning! Feel me? I hope so. Good luck.
