I'm not sure if you're a minor or not (not saying you are, just being cautious), so for the record the below spells are for adults only:
Love spell
Sex magick
Going to the gym or moving your body (even just walking) can help with self esteem and also motivation. It teaches you what it means to have discipline and structure in your life. If you can save up for a PT session, they will show you how to use the machines so you can work out different parts of your body.
Getting a haircut is also nice, it shows you like to look after yourself, you could try different ones until you find what suits you.
I would also recommend saving and getting yourself some nice deodorant and aftershave, just use it sparingly like a whisper.
As for talking to people, you could find activity/community groups around you, or potentially interact anonymously online in metaverses to begin with (social rules are different online - it's usually fine to walk up to people and start talking, lol.).
